Mark's place is a gem. It has great style, it's clean, and it's an easy walk to the Brixton market. I would definitely recommend it to others.
Mark was nice enough to meet me near to the subway exit, and walk with me to his Airbnb. Along the way, he gave many suggestions to local places and he was very friendly and charismatic.
Upon arriving, I saw the room and it is a really nicely decorating, cozy, clean room with built-in book shelving and tasteful, artistic touches. The bed was extremely comfortable, and for a Saturday night, I slept great with minimal noise from outside!
