I spent three weeks in Pratik's house when I arrived in London and I had a very nice stay! All the staff at the reception were especially nice and available at anytime of the day. The shared kitchen has not a lot of cooking supply, but the basics are here. You can hear a little bit the neighbourgh, however the street is very calm and the park in front of is nice.
If you are a clean freak, it can be a little bit messy, however i am not sure you can find so much better at this price and location in London.
