S15 Sukhumvit Hotel in Bangkok

I stayed at S15 for 7 days and it is a very nice hotel. The rooms are spacious the bathroom was huge with a shower and tub. I also used the Massage Spa on site and the aroma Massage 120 mins was heavenly. The only thing I can say I was disappointed in was the gym. They have minimal equipment which was fine but I'm a gym nut so just wish there was more. They did have a hot and wet saunas so that made up for it. I would definitely stay again if I travel to Bangkok many things around and close the the Skytrain so too many benefits. Last thing which I should have mentioned first was the Staff...very friendly and accommodating top notch service.

Good room, comfy bed, clean place, but noisy at night bc of the road, even with earbuds i could not sleep. Breakfast is ok for this price, but a bit stingy on some points, for example, coffee provided in the room, only one capsule, while we booked as a couple. Asked for extra towel, got one only. Night service should be more customer friendly, felt like annoying them for a simple request... and customers remember that feeling more than anything else...

Good hotel in a great location just 7 mins walk from Asok station. I will say that the rooms can get quite noisy even at night since it’s right by the main road. I could even smell some street food from my room so maybe request one of the higher floors if possible. Otherwise, I had a wonderful stay! Sure the design is a little dated but the staff are helpful and there’s a tub for you to soak in after a day of shopping.

Let me start off by saying what a wonderful time I have enjoyed here at this hotel over the last four days. It has been surprisingly wonderful, let me explain.
For some context I'm just an old white guy 64 years old that has traveled most of his adult life for work. At the end of my career I started traveling for leisure. So most of my reviews are from the context of a traveling worker and in other words I'll worry about the things that keep me productive. With that said, my selection of this hotel was on reviews and on location. It's really short distance walking to terminal 21 which is one of my favorite shopping places. For those of you interested it's just around the block from the Thermae cafe and the Softel Hotel. With the coffee shop next door and a Burger King next door, no I don't eat it Burger King but it is convenient. Additionally there is the seafood house maybe 2 1/2 blocks down the street still well within walking distance that is so good and so cheap. Don't get me started about the food around here which is incredible and cheap.
The S15 hotel is a small hotel, I would call it a boutique hotel. It has a premium location and a wonderful facility. First the staff are all very accommodating everyone's speaks fluent English and are well versed in the local festivals that are currently going on which currently happen to be a few. Sadly we are here during a period where the queen has just passed away. So that means the country is in mourning and some things will be different than previous.
The hotel has a great lobby a great garage in the back end although things seem somewhat cramped they're not. Moving further up into the room. I enjoyed a room on the third floor which was bigger than normal complete with leather sofa kind of a lounging living room area kind of thing at the foot of the bed very nice I was very pleased with it fully stocked mini bar total high speed Wi-Fi everything's available including room service into and past 10:30 PM. Had room service last night that was just phenomenal. Other wonderful things about the room are the rain shower head, which I gotta tell you I'm rapidly turning into a fan of. All the linens are new and updated all the towels are fresh and fluffy the bed is wonderfully soft I overslept way too much.
The second floor breakfast, oh has surprised me. Of course eggs to order bacon sausage everything American as well as lots of Asian and Asian fusion type breakfast materials, fresh fruit drinks smoothies and of course a cappuccino when you're done. All of this from the second floor where there's a wonderful view of the street. The morning breakfast was a stunner. I was amazed at how very good it is. Well lit and sunny, staff always accommodating the food was impeccable. My hats off to the chef and his staff for an outstanding experience, consistently every day. I can't say anything negative about it. A wonderful dining experience a wonderful breakfast experience. I will come back for the breakfast.
Yes, I will come back to this hotel. Probably during this same trip for a few more nights. This hotel offers everything that a traveler could possibly need and then some from location to staffing to facility to the linens. This hotel is in my humble opinion a five star hotel living under a four-star banner.
I will update this review upon my return to this hotel which will probably be just a couple of weeks from now.
Thank you for taking the time to read my review.

Excellent location right on Sukhumvit. Next door to a 24 hour coffee shop, Terminal 21 about 2 blocks away, BTS station minutes away, across the street from the SW1 night market, and numerous other food options ranging from street food to high-end dining.

Staff was incredibly nice and very quick in checking me in. Breakfast was good with a number of options. Room was spacious and the bathroom was pretty cool with the fancy smart toilet.

Can hear the nearby BTS but did not affect my sleep. Blackout curtains did a great job of blocking out the light for those daytime naps.

We had buffet lunch which also consisted of authentic Japanese cuisine, all for the price of 275 baht per person. The waiter's were well versed in appropriate methods of having the various cuisine available there. The only seemingly downside was that they opened around 11am and closed near 2.30pm, so we had to rush a bit.

Good quality boutique hotel. Walk in reservation during peak season and was lucky to get a room. Suite room was very comfortable. Check in seemed to drag on a bit. One of the best breakfast buffets I've experienced in Thailand. Outside bar is a good spot to watch the world go by. Cocktails a bit hit and miss. Excellent location with everything you need in walking distance. Be happy to stay here again.

Friendly staff, very clean facilities. I did not stay here, just attended a meeting. Everyone was helpful.

Came here for the lunch buffet. For just $10/275baht , you get a decent selective of food with decent taste. Worth coming here to have a quick lunch if you are in a rush. Dont held too high expection on food afterall , it only worth $10
