Fantastic flat. Great, quiet location. The flat is well kept and appears just as in the photos. Overall, I highly recommend this as a two bedroom flat in central London.
For check-in, they want 24 hours coordination, which candidly is less than ideal when often travellers do not know precisely when they will arrive. It would be better to have a self-check in system, as there is nothing complicated in the flat and self-check in would work much better. The host looks after many places, and whilst I understand that coordinating check-ins must be tricky, at the same time, in a service business such as Airbnb hosting, you must accommodate the guests' needs not your own.
The host was great and moved things around to accommodate our check-in at 5:30 after first saying it was impossible to check us in after 4:00 (even though the website states no-checkin before 4:00). The host's flexibility and ability to accommodate us more than made up for the initial annoyance.
