We had a great stay at Jim's place. You can tell that Jim is a host that pays attention to detail: the apartment was well equipped, with useful notes around the place to help you know how everything works; we stayed for 3 weeks and felt right at home.
The location was unbeatable; we never spent more than 30 minutes to get to any centra location in London, the train station is literally 1 minute away and there are also plenty of bus options, even late at night.
The farmer's market on Sundays is really nice, the park is 5 min walking distance, and there are plenty of good food options nearby. Two supermarkets are 5 min walking.
We recommend this place 100%!
