I stayed one week at frank's locations.
Frank is a great guy. I enjoy our talks. He is a new host and is just learning the airbnb ropes but I can see he enjoys hosting.
The kitchen is excellent for cooking and the room I had was very large.
The house is located 2 blocks form the cute area of Stroke Newington this is a safe family area with coffee shops and bakeries. The bakery at the corner of frank street is my favorite.
The 76 bus on the corner take you to soho (center of London) in 35 minutes they leave every five minutes.
I found this to be a great value. I would stay again next time I am in London.
