Good room for a short stay. Really good location - it was easy to get to the center and to get from it (Upton Park is a short walk away, and there are frequently-running buses even closer). The room is on the ground floor near the door so it's perfect if you want to easily get in and out (I was also given a key so I could come and go any time I want). Not perfect if you're a sensitive sleeper because I could hear a lot of noises in the house (especially if someone is leaving through the front door) & from the street. I was fine and got used to it pretty fast, but it's just something to be aware of.
Also, the room is warm enough and this is great!
Overall, if you're going to London for a few days and aiming to spend all your time in the city and come to the room just to sleep, then it's a good choice and a great price!
