To start with the postive: the location is ideal, 5-7 minutes' walk from Paddington station in a beautiful street. Check-in and out went smoothly, as did contact with the owner. The room was clean and tidy.
The room is very small, as mentioned in other reviews and as you can also see from the photos, so be aware of that. It is very nice to have a kitchenette. Especially since a supermarket is around the corner. There is no room for extensive cooking, but the microwave and hob work fine.
The room did have some problems: the floor is swollen with moisture and every time you walk on it you push that moisture out, so you always have wet feet. The shower head was a lump of limescale and the toilet seat needs to be replaced. The other big problem was the noisiness. My neighbours loved having conversations into the early morning and I could listen in. Earplugs are required if you want to be able to sleep.
All in all, not a bad experience, but not a fantastic one either. With a bit of renovation, I would recommend this room.
