Valentina was a fast and excellent communicator. She allowed a late checkout without issue. Self check-in and check-out is very easy (pickup keys from Piazzale Roma) and there is NO late check-in fee. Tourist tax is paid in advance online.
Location is excellent and directly on a canal opposite Ponte dei Pugni (8mins walk from key pickup in Roma). There is the vegetable/fruit boat next door, bars/gelato/bakery/supermarket 2min north, restaurants 1min south, 5min to various ferry terminals, and you can walk everywhere else in central Venice in about 20mins.
Flat is very comfortable and clean. It is safe, quiet and on 2ND FLOOR (no lift). Wifi is reliable and fast enough for video calls. There are 2 aircon units (1 living room, 1 bedroom portable one which needs the window open) which work ok.
Overall very comfortable and I would happily stay here again.
