Carlotta met us near the apartment and explained us everything we may have needed. The apartment is just perfect, very comfortable and clean and beautiful. Carlotta filled in the refrigerator with a set of food we may need. It's very sweet of her.
The place is not touristic but there are enough shops/supermarket/cafes around. Firstly we went to the historical part and back by foot but I would recommend to make a photo of a timetable to the buses (11,36 or 37) and get back to the apartment in the evening by bus because well it's up the hill.
The place, the apartment and the host are perfect and I would highly recommend the apartment.
