Reviews
Clean, comfortable, and well located. Friendly staff and a very pleasant stay. Would definitely stay again..
All soaps/washes and creams are vegan!
Food was impeccable! Highly recommend the carbonara and the buffet breakfast is not to be missed. Absolutely unreal!
The staff are fabulous friendly and helpful too!
We didn’t use the pool as it’s early December too cold! Spa and gym are also amazing. Just what you need in there! Super impressed.
I wish I could give more stars but based on my experience I really can't. Before I continue I have to note that the only thing that I found nice was the staff.
First thing I would like to note is the price which when you look at it it seems nice but considering that breakfast is an additional 19 eur per person and per day, the price is a bit ridiculous. You can pay just a few bucks more and get an hotel that's closer to the center and has breakfast. Another downside is that the rooms are chosen by "preference" and there is no assurance what kind of room you will have until you arrive. When I contacted them in booking they did not give direct answers but rather long tamplated messages that can be confusing for most (so was for me that I mistook it as breakfast included).
As we enter the room it was not that dirty in general but there were spots on the bedsheets. Another thing I have to note about the room was the shower head that was broken and also the plate.
WORST THING that happened was that when we we were waiting at the hotel lobby one of our bags almost got stolen by two thieves that were comfortably sitting in the couches. If we hadn't seen them for a second we would have lost our passports and credit cards. It's ridiculous how they could so easily stay inside the hotel and try to steal your stuff right in front of you. It's not normal for hotel security to allow this to happen.
I didn't use all hotel facilities so I definitely can't speak about everything. This may be a unique personal experience but I believe it's best to share so everyone is aware.
