The apartment is really nice, very close to the tube and Kensington Palace.
It was a little bit hot at nights, we couldn’t figure out the heating system, and the elevator doesn’t work. So if you are going to go with someone who’s not able to go up the stairs, this is not the place for you.
Overall the apartment is beautiful and the neighborhood is really nice. We stayed in the biggest room and it has plenty of space for 6 people.
