I used to live in London, and can attest that Adrian's place couldn't be in a more prime location for easily accessing major sights. It's directly off the 24 bus (which runs 24/7), and thus a short ride to central London and other major connections.
The space is immaculately clean, and the access to the kitchen in the morning is an excellent bonus. Adrian is very communicative and thoughtful with his space and hospitality. Can't recommend it enough.
