It was better than expected! The room was spacious and the bed was very comfortable. The staff was super lovely, helpful and welcoming! One small note: when I entered the room, there were big chucks of crumbles on the floor. I guess it wasn't properly cleaned, but the next day the cleaners took care of it. No worries, can happen :)
Also, they have a large TV in the room and the remote said “smart” so I could log into YouTube, but not into my Netflix account. That was a bit disappointing, but I’ll give it a 5/5 anyway, because overall I had a great experience staying at this hotel.
There's a great Asian restaurant (2 min walking distance) called Mai Garden. Lovely staff and delicious food! Just know that the supermarket (below the hotel) and stores are closed on Sundays and bank holidays.
Another small note to the ladies: do not go out alone after midnight (as a woman) because I experienced it as quite dangerous (people might harass you) and there are no Ubers in Basel..
