I stayed at Peter and Melanie's for a week. Peter met me at the door, helped me with my luggage, and showed me to my room, which was huge by London standards. I had a desk and a chair to work at, as well as a couple of plush armchairs that were great for reading in. There was a fan for the warmer nights, and the bed was comfortable (if a tiny bit creaky). The location was brilliant, just a short walk from the station but with the City Bike Share right outside the door, I barely used the Tube at all. Peter went out of his way to provide WiFi when there was an outage, setting me up with a 3G dongle and even tethering from his phone. As I needed WiFi to work, this was very much appreciated. As advertised, the place is no-frills -- it's an older building and the bathroom and kitchen haven't been recently renovated. But the location is fantastic, the room was spacious, and for the price, it would be hard to do better in central London.
