The flat is definitely nice and very central. you can reach Backingham Palace, Westminster Abbey, as well as other important sites in London within a 10 minute walk, so top location!
But as of today, 13th September 2022, the photos you see on airbnb show a different flat (which is still nice, but it's only fair to point it out), starting with the view: there are no trees, but a beautiful church.
There are no locks on the doors of either the room or the living room where I slept, only on the front door, which remains shared with the host. This does not seem right to me from a privacy point of view of the host, as I want to be able to lock the spaces where I sleep to keep my stuff safe and be more comfortable when I am out. To give an example, I happened to walk into the living room where my sofa bed was and found the host. OK it's the living room of his house, but if I'm going to sleep there I would at least want no one to have access to where I sleep. Instead, the lock in the room where my parents slept is necessary.
I report that at the foot of my bed I found a basket with other people's dirty laundry, not very professional. The host then is always in the kitchen, so it is difficult to have the freedom to go and cook something without disturbing her.
