Has the feel of a hostel, but without having to share a room with too many others. Since it's not clear in the listing: "4.5 shared bathrooms" means 3 (or 4 by the time you read this, since one was being installed during our stay) showers and 3 toilet stalls connected to a room with two sinks. No paper towels provided for those, just a couple of hand towels, which I was not entirely happy about sharing with the 7 or more other visitors in the building at the time, even if they were being replaced every day. The hot water worked most of the time; be careful at the kitchen sink, it gets hot very quickly!
A decent base for a tourist trip to London, and the Turkish restaurant Efes down the road was excellent.
