Really great stay at Sam's flat. It's perfect for 6 person with 2 bathrooms, 2 bedrooms with respectively 1 double bed and 2 single + the convertible in the living room.
The living room itself has a good size.
Flat is 1mn away from the entrance of Edgware road station + a bus stop 50m away from the door. So everything is quite easily reachable. Location is ideal for a stay in London.
Only missing thing: no "starter kit". No salt / pepper / coffee to help the stay so we had to buy everything. But appart from that slight inconvenience, everything was great.
