We really enjoyed Barry's flat! We didn't meet him, but we collected the keys from a friendly lady in a house just a few doors away.
Unlocking the door the first time was a bit of a puzzle, but it was fun.

The flat is spacious and luminous, with large windows. Beds are extremely comfortable (probably the best feature in terms of furniture/accessories). The kitchen is functional and we found milk, several tipes of teas and infusions, sugar and other stuff.
Wi-Fi, big TV, books, games and DVDs are a nice addition, especially if you need a bit of rest.

The building is quiet and the neighbourood safe and leafy, very near to the shops and the tube (the wonderful Northern line takes you almost everywhere in central London). There are also at least a couple of buses - N5 takes you home straight from the centre (Leicester square, etc.) if you miss the last train.

Highly recommended.
