We had a great time at Katya and Daniele's apartment. We stayed for two weeks from a little before Christmas to a few days after New Year. The apartment was exactly how it was decribed. Centrally located, bright and airy, all necessary amenities (kitchen stuff, washing machine, internet, heating, etc) up and running without issues.
But really, the best part was Katya and Daniele themselves. They were always super responsive and helpful and always nice and polite. At check-in I had pestered them with ten different questions: "how does this work" or "what do we do when this happens" and they were always very patient all throughout.
We were travelling with our one and a half year old son and at some point he broke something but when I offered to pay for the damage, Daniele just waved it away. At that moment, I really felt like I was visiting family. I had no words.
If you want a no frills centrally located fully equipped family friendly apartment, this is it. Bonus: Superb hosts.
