My wife and I loved our stay here. It was like staying at a friend's house, instead of the clearly not-lived-in flats that make up so many Airbnb's right now. True, you don't have an empty closet to fill with your stuff, but instead you have a nice collection of books, spices, and other items that give a glimpse into local life.
The kitchen is very well equipped, and there are multiple food stores within 10 minutes walk. We preferred the M&S that was a little longer walk but had much better selection.
The flat is in a very quiet location, with almost no street noise as it is on a dead-end alley (minus the morning of garbage collection day!). We slept very well.
The wall heaters kept the flat at a very comfortable temperature, but if you are there during a heat wave then note there is no aircon.
The location is splendid for exploring London. There are two tube stations and a major rail station within a short walk. You can walk to the Thames in 10 minutes, and Borough Market and Big Ben are about 15 minutes (in opposite directions). Plus there are a ton of restaurants nearby.
We loved it and would stay again!
