All in all, not good. We booked the flat because we wanted somewhere to stay in and cook on a couple of nights and the flat wasn't nice enough to do that, which was a real shame.
The sofa was broken(?) so quite uncomfy, and didn't smell great. The kitchen was sort of smeary and a bit dirty? The floors were all quite dusty and a little bit grimy. It's a small thing but the mirror behind the sink was splattered (with toothpaste from previous guests).
The shower was actually the worst I've showered in. Incredibly cramped (like, really tiny), poor water pressure and a fan with exposed wires (!!) just above it.
Also the bed was very uncomfortable, which wasn't ideal. And Francesco and Federica had mentioned a view from the balcony when I asked, which in fact was a view onto some roofs opposite.
Francesco and Federica were very friendly on check in and sent us a good activity recommendation. I didn't much want to raise any of my issues with them while there (they couldn't have fixed the main issue of shower and bed!).
The flat was in a very good location (next to the botanic gardens; close to 2 lovely places to get breakfast; a short walk from lots of restaurants/bars). The air con was good. Very minor street noise; it's on a quiet street.
All in all I wouldn't recommend staying here. Even if my standards of cleanliness are too high, the shower and bed were objectively not good.
