This is a very clean and nice apartment that is within 3-4 min walking distance of Gloucester Road tube. Sainsbury's located downstairs is very convenient. Building has 24hr security with elevator. Only thing you need to be informed of is that the apartment is split into 2 levels. There is one ensuite bedroom on the level that you enter. And then the living area, kitchen and second bedroom are all one level below. And there is no elevator within the apartment. So you should be willing to navigate one flight of stairs everyday.
That being said, Matthew is a great host and did make our stay very comfortable.
