Neil's home was perfect for my group's needs. I was traveling with my family and a couple of friends (7 total), and stayed for 4 nights. It is in the perfect location. Only a 5 minute walk from the tube station that will connect you to so many places in London. It will usually require a transfer or two, but it's pretty easy to navigate. FYI, Neil's home is spread over 3 floors (4 floors, if you're used to the ground floor being the 1st floor). It's very cozy and we really enjoyed our time.
There was plenty of room for us to move around and we never felt cramped. The kitchen was perfect for cooking several meals during our stay. We purchased groceries from Waitrose, about a 15-20 minute walk away through residential areas. There are convenience stores closer to the rental, but aren't well equipped if you plan to cook a well balanced meal.
Neil was kind enough to push his meeting back an hour because we were running late (very long lines at customs and for train tickets/Oyster cards), in order to let us into the house. He was able to offer suggestions for places to eat (we love food) and we ended up going to Captain Kidd (good pub-style food) and Il Bordello (old school Italian, ended up their once for dinner, and once for lunch!).
Anyway, if you decide to stay at Neil's, I'm sure you will have a cozy and relaxing time. The best thing I liked about it was the location. It's in zone 2 but away from all of the city traffic.
