The location is excellent with all the main sites only a very short walk away.
The welcome from Frederico was good. It was cold to start with but some adjustments to the thermostat by him and then by us got us warm. An extra duvet was delivered within a few hours of our arrival as there was only a thin duvet and thin blanket.
The apartment was very clean and well equipped. We only ate breakfast there as there are so many excellent restaurants and osterias nearby.
The main living room and the bedroom are both very large and comfortable. Most of us like a second pillow and the memory foam pillow provided for each person is very hard.
The bathroom and kitchen are fine, though rather dated by modern standards. They are fairly typically Italian - we travel widely and have our own house in Italy.
