The flat is perfect for one person. Everything you might need is there and if you miss something, several supermarkets are right around the corner. Wifi is good and the kitchen well equipped.
The location is superb. You can reach everything by foot. It's right in the touristic centre, but in a quiet side street. At night, it is very quiet, though I had to get used to the early morning (6-7am) deliveries to the surrounding restaurants.
Alberto is a perfect host, he is super helpful with orientation, infos about the city and happenings.
I really felt like a local for a month and I can fully recommend the place!
