Pros: Great location, very spacious, responsive host
Cons: A few minor issues like incorrect wifi information, no laundry detergent, etc. The host did resolve each of these things though so nothing major. The only big con that I had was the noise- the bedroom is away from the street, but it is right next to the staircase for the apartment building and the walls are paper thin. Most days it was not an issue, but on a Saturday night at 3am people were very loud, presumably coming back from bars.
This is a good place to stay if you 1) are a heavy sleeper and 2) value a large space more than everything being exactly perfect from the start.
Personally if I returned to London I would look for another place, but it was by no means a bad stay.
