The Pros: The flat is in an excellent location and is a good size for 2 couples. The bedding is comfortable and the flat is in good condition.
The Cons: The key pickup/dropoff is very inconvenient. It's a 10-15 min walk from the flat which is a bit much if you are arriving from a long trip or need to take off early in the morning to catch your plane home.
The amenities in the flat were very poor. They left no shampoo, conditioner, dish soap, cleaning supplies. There was a bottle of raspberry glitter body wash that looked like it had been left by another guest. I'd expect a listing of this price/calibre to have hotel level amenities. Having no cleaning supplies is inconvenient when you are staying for more than a week and there is no cleaning service.
The host left no welcome gift or note (it was over xmas as well!), I know this is a small thing but I've never stayed in an Airbnb that didn't do that and I've stayed in many. Overall the flat is sufficient but impersonal and slightly inconvenient.
