Adrian's place is THE place to stay at. The location is unique, near a bus stop, a subway station and you can easily walk from there to Buckingham Palace!
Adrian is a wonderful host. My plane got terribly delayed but we kept each other updated and everything went very smooth and easily. You share the common spaces (bathroom and kitchen) with the host and the people from the other room (there are 2 bedrooms for travellers). The room is really cosy, and has everything you need. You can even help yourself in the kitchen for breakfast! Adrian was extremely friendly, had thought about everything and gave us some useful recommendations .
I'd definitely recommend Adrian's place to all travellers coming to London!
