The building is a poorly-worn walk-up and is not well maintained. The halls and unit had an unpleasant odour, which the host's solution was by opening a window in the winter during the check-in showing. The waste bin had not been emptied. No self-check-in. If it was my listing, I'd have dealt with the odour. I didn't accept the keys, left, and got a hotel. So not a great deal for me.
If a listing only has close-up photos, expect it to be small.
The listing at the time didn't show the exact address, which is on the only noisy street in a genteel area of Central London. If I'd seen the exact address, I'd have booked something else. The host responded to my correspondence by claiming I was lying about the unit, which I didn't particularly enjoy.
