First things first, because I feel like this is one of the most important points to bring up, this isn't a hotel in and of itself, it's part of the Phoenix hotel 3 doors down. It's its own standalone building though with 15 rooms split on 4 floors. Check in and check out happens 3 doors down where they have 24/7 front desk and an actual lobby and where it actually feels like a hotel. The Kensington Garden isn't a hotel, just a branch with studios of the Phoenix hotel, strange but I guess that's okay.
The stairs are steep and challenging especially if you are placed on the 4th floor. I am young and healthy, and it was a hike, I can't imagine older folks or those with physical limitations. Unfortunately, this is the truth for a lot of these hotels in London.
The room was exceedingly small. Once you opened the door you were in this 3 x 7 rectangle with a tiny door and a 2 x 2 restroom. I couldn't move, I am a 6'2" big guy, you can imagine the issues I faced. I barely fit on the small twin bed, and I could not take a proper shower because I barely fit in it. As for the toilet itself, I had to sit at an angle with my legs in the room in order to fit.
The door had a sliver that allowed me pretty much see on the landing and I could hear my neighbors as if they were there in the room with me, loud and clear even when they were just having a normal conversation, I heard every single conversation clearly.
This hotel's only saving graces are its location and cleanliness.
