Sam's place is perfect. She has made the small space into a tidy, cozy place to rest and return to. We found it better even than the pictures indicate. (In fact, there is a wide entrance lobby, shared with Sam; the guest kitchen is off of that, outside the bedroom. This gave the place a more spacious feel than we expected.) The kitchen itself is very well-appointed, everything you need and more. The bed sits under a window overlooking the back garden and is surprisingly quiet and nature-y. There is a good cafe just across the street, several groceries, and a tapas restaurant, and on the next block, more restaurants, a great bookstore, and more. Sadly, we ended up being sick and hardly left the area during our time there; thanks to the coziness of the bedroom, the ease of the kitchen, and such close access to coffee, tea, and food in the neighborhood, we were able to manage in a way that was enjoyable, despite not feeling well and missing out on touring central London. Sam herself is a delight to meet and talk with. The whole experience was very good. We would definitely come back.
*note: if you are traveling as a couple, you'll find there isn't a lot of room for two people's luggage. We managed by sliding one of our suitcases under the bed and keeping the other in the hall by the bathroom door. It worked just fine, but we were traveling with very small luggage. If you come with large luggage, be prepared to get creative about storing and accessing it.
