The flat was good and Like described. The AC worked very Well.
Only Problems were that the Check-in is organized via a third-party which needs you to announce the Details of your arrival a few days earlier, an Important fact we only learnt about the day of our arrival. We still were able to Check-in after some communication with said third-party organization. The other issue was a weak smell of canalization from the tap, but it wasn't very Strong and probably not preventable regarding that we're in venice.
Still worth the price and definitly good enough to spend a few nights.
