The apartment has a great view from the thirtieth floor and a convenient location near the Underground (so it is easy to get into the centre of London). It is easy to find convenience stores and some restaurants in the area.
The kitchen is well equipped and it was nice to find salt, tea and other leftovers from previous visitors.
We were able to check-in earlier on the day of arrival, which we really appreciated. James was a great host, and answered to messages immediately.
We only have two concerns with the apartment.
1) We travelled up to a heat wave in London, so we never accomplished to get under 31 degrees in the living room. So it was not very comfortable for the person sleeping in the living room.
2) The other concern is the sofa bed in the living room. The cushions are worn out, so you can feel the wood frame, when you sit or sleep on it.
I recommend that you only stay two persons in this apartment so you can sleep in the bedroom and avoid sleeping in the living room due to the heat and bed in the living room. Then I think you will have a really fine stay.
