The location of the flat is fantastic, close to great restaurants and bars, not too far from public transport. The building is very secure as well, we were staying with our child and felt like the flat was very safe.
The flat is pretty big for London, with two big bedrooms.
The communication was very good and the owners were really flexible with check in times and providing extra bed linen.
The down side for us was that we felt the place was a bit messy for an airbnb. Considering the price, we thought the flat needed to be presented a bit better. But still a good place to stay if location is the most important thing for you.
