John's place is really lovely, exactly same as the pictures show (actually more comfy then be pictures! :) ) John sent us a very detailed guide before we check in, which makes us very easy to find it.
Highlight: You have you private access to enter you room and your private bathroom to use!
Also, it's very easy to go around with bus station (3-5 mins walking distance) and Old Street subway station (10-15 mins walking) nearby. And there is a Starbucks next to the subway station.
Very safe and quite neighborhood as well.
I would def come back again if I visit London in the future.
Many thanks!
