I spent great 2 weeks at Johnny's flat!! He is definitely a great host: kind, helpful and sociable. He offered everything what I need.
The flat is also really nice. It is clean and comfortable. You can go to the middle of the city easily by bus (No. 29) or tube. Moreover, you have Morrisons and Waitrose in 10-minute walk.
If you want to stay at a brilliant flat in London with a splendid host, I highly recommend Johnny's place.
