Great place, very clean, well looked after, and the hosts give you privacy while keeping in touch to make sure you have what you need.
The only drawback for us were the multiple imperative notes around the flat ("Do not" "Keep closed" etc etc) which when combined with other elements (check-in info is given precisely 30 mins before check-in time) made us feel more "controlled" as potential hazards to the flat rather than welcomed. This might be a cultural difference, and be ok for some though.
That being said, if you're looking for a quiet night in a clean space on the way to the airport, it fully delivers.
