Well, firstly, we have had to cope with the worst floods (acqua alta) in decades! Thank you for the wellies!
We loved the architectural touches in the flat, its location (off the tourist areas), heating when we needed it, and the local amenities (shops, fruitstall and bakery). The flat was super-clean, and quiet too. We had a perfect host, giving us clear and prompt communications, and it was excellent value for money.
All in all, perfect for a small group of architecture professors...!
