We had a wonderful stay at the B&B Allogi Serena.
One of the most important things for us was the possibility of checking in late(ish), because of the timing of our flight. That was no problem here.
The bed was super comfortable, the breakfast, prepared daily by the lovely Marcella, was more opulent than expected. Communication was easy and fast via the Airbnb App.
Just one little thing that I would like to bring up for any future stay - we wanted to pay our city tax, as noted by Sergio, in cash. But there was no change and we were asked to go get the change ourselves over the course of our stay. That is not a big problem but unnecessarily inconvenient.
Besides that - Sergio and the B&B get an absolute recommendation.
Grazie mille!
