My wife and I stayed for three nights.
Chiara welcomed us warmly to the apartment with coffee and a cake Lucia baked. The apartment was very clean and in a perfect location. You just walk 30 seconds and you find yourself in the middle of all that magic. Those 50 meter from all the action make the apartment surprisingly quite.
We had heat issue on our first night which solved on the morning after (heat valve outside was left close). Chiara helped and made the arraignment for transportation from and back to the airport and was very communicative throughout all our stay.
The location is amazing, the hosts are great. We recommend the place to all.
