The good:
The apartment was spacious with 4 bedrooms and a living / dining room.
Checkout was easy with only thing to do is drop off the key into the lock box.
The not so good:
The shower was really small, the tiles dirty, and the grout moldy. Small shampoo and soap bottles were provided, but there was no space to keep them in the shower except the floor.
The mattresses seemed really low quality with the springs felt in our backs. This was not comfortable.
Communication with the host was disappointing. A few days in advance, we asked if we could check-in earlier, but no response.
I know London is pricey, but when we pay over $500/night with taxes and fees, we expect better than this...
