I stayed here for six weeks Oct/Nov and was welcomed by Francesco's mum on arrival. The apartment is as described and although small has everything you need for a comfortable stay. The heating and wifi worked really well and there was always hot water. Francesco, Nina and Francesco's mum were friendly, helpful and easy to contact for any questions.
Although the area is quite busy and central to everything the apartment is in a calm and peaceful courtyard and I felt very safe staying there on my own. I would stay here again.
