The flat is nice and clean. Communication with Marcello was quick and easy and very friendly. The location is perfect if you want to visit biennale and on via garibaldi you find everything you need- Supermarkets, Bars and Cafés. Castello is a very nice and quiet neighbourhood with a lot of locals. The only bumper was the Aircondition on the Roof of a nearby hotel. It was really really loud and you have to sleep with windows and shutters closed, which is ok in autum and winter but summer might get really hot. Keep that in mind and bring yourself some earplugs. All in all a very nice experience but a little pricy for what you get.
