This flat is in a great location very walkable to Hyde Park, Marble Arch, Marlebone and Soho and with many cafe's and grocery stores within a 5 minute walk. The architecture of the building and interior detail was great but renovations across the building, and on the same floor, contributed to a good deal of unexpected noise (early morning and late night). Overall the flat could have been cleaner and the interior better maintained.
The host was great though, and very responsive, providing us with a space heater due to an issue with heating in the building, as well as some plug adapters since the airline had lost our luggage.
Guests should be aware that the key isn't available onsite and must be picked up in (and then dropped off to) a location which is about a 10 minute walk away, and during certain business hours. Overall, we had a great stay for 2 weeks.
