The apartment was nice and felt very safe. One bathroom was cold and dark, and the tiles in front of the toilet is broken so it feels like falling trough the floor at first. So its good to keep it in mind.
But the living room and the bedrooms was good. Usually visiting London its not for sitting inside the apartment, so where the apartment is, is the most important for us. It was very close to underground and train station. The neighbourhood was nice, its calm but at the same time it has a lot of restaurants, shops and whatever you need . Its just few stops from oxford street and the other more busy places. Also close to hyde park, that was a nice walk for us.
We would stay again.
