The location is very central and is great for shopping and for tourist related activities. Marble Arch underground station is nearby or you can walk directly to Bond Street station which has more lines running to it.
The inside of the apartment was the same as the photos and staying there was very comfortable. The apartment central heating was warm and the hot water for showers was perfect.
The only bad points were more related to the security side. Perhaps the host could provide another set of keys for the other locks on the door. Also, the letter box unfortunately on the door can be opened and you can look within the apartment from the outside. We ended up draping a towel over it just to get a better sense of privacy.
As others have also mentioned. The cars at night can be quite noisy for the room that faces the main road. I think this is acceptable given the location.
Overall my family loved staying at Jack’s apartment and would be happy to stay there again in the future.
