We received a warm welcome from Nicola who was most helpful. She provided us with information about the accommodation and the locality. The flat was as expected and the terrace was wonderful. Trastevere was a super location - walking distance to all the tourist attractions and yet quiet at night, with a bakery on the doorstep and a lovely local market 15 minutes walk away.
On the last morning we heard the nuns from the nearby convent - see bell tower - from the bedroom windows.
Davide was extremely sympathetic when we had to change our reservation due to family illness; we really appreciated his kindness and understanding.
I shall be recommending this flat to my friends.
