Hotel AMANO East Side in Berlin

Very poor.
Shortly: Horrible customer service, no room cleaning, rooms are disappointing.

So I paid 230€ per night for a simple room in this hotel, and I feel robed, because the hotel was not even close to the 3 stars that is stated here in google. This hotel should have no stars.
They suggest you do check-in online, and give you a virtual key so you can open the room with your phone. Surprise: this key doesn’t work. You need to still ask for it at the reception.
Service at the reception is not welcoming, feels like guests annoy the employees with their requests. When I asked for additional amenities to be brought to the room (a toothbrush), I’ve been told I need to go to the reception and pick it up. Not the service you expect in the hotel of 3 stars or similar.

Room is small and dark, very little light from lamps, and lacking cleaning: there is dust of many weeks on the lamps. The pillow is super flat and uncomfortable, there are holes in the bed sheets, and the mattress is uncomfortable as well.
The basic room doesn’t even have glasses for water. There is a sign however that you can drink tap water, very thoughtful to put the sign and no glasses to drink it from.
In three nights that I stayed there, the room wasn’t cleaned. Hotel clearly wants to skip cleaning as much s possible: the tablet in the room asks you to confirm you want to skip cleaning almost the first thing after you enter the room, and the standard door sign with „please clean“ doesn’t exist, its place took a sign with „please skip cleaning“ (on the other side „do not disturb“).
There was no cleaning done in the room in the three nights I stayed. While on one day I put „do not disturb“ sign for a bit of time, it wasn’t there the whole day, and the team had time to clean. Next day I asked for fresh towels, saying that the room wasn’t cleaned yesterday. They brought towels, but that day the room wasn’t cleaned again, although that day I wasn’t in the room most of the day and explicitly left the room without any door signs. When I communicated this to the hotel, they say that I lied and there was always a sign of „please no cleaning“ or „do not disturb“ on the door, and they do not care what I say. This tells you a lot about the customer service in this place :) I travelled a lot, but this was just a horrible service.

The only good place about this hotel is location. For the rest - really really bad. There is basically no service, employees are annoyed by guests, there is no cleaning in the room, and even no basic things in the room like glasses for water (of course also no coffee or kettle, but well apparently they write it in the room description. Although for the price and level of the hotel it’s unacceptable in any room). Stay here only if you like overpriced super basic rooms and absence of customer service.
