It was a great location for us as we traveled from Milan by train and bus (from/to airports, Torino, Stresa, outlet Serravalle) from Central station which is 15 min walking from the apartment. The area seemed nice and safe, 2 supermarkets within 5 min walk - Tigros and Carrefour, would recommend restaurant St. Mina - very affordable good food. On Friday morning you can buy some fresh fruits, vegetables, sea food, cheese etc. in the market that you walk into the minute you step out of the building. Metro is nearby, though if you feel like walking you can also go to the city center by foot (not too close though).
The building is old and beautiful inside, apartment style really matches it. Shortly - you feel like staying in one's house (which I guess is actually the idea of airbnb). You get maybe even more than you need in terms of some details. It was a pleasant surprise to see some stuff for breakfast. Everything we needed was there. I only noticed there is no TV after couple of days, and as I don't need it, it's fine. There are many books, pictures, pieces of decoration. There is a little balcony overlooking the yard. Can be noisy when people throw glass in trashcans there.
What was not very convenient is that even though you have 2 rooms they are all interconnected. Basically, a straight way from corridor to kitchen, then to the room with 2 beds, then with 1 big bed and only then bathroom. If you stay with a friend in the other room, it's not very cool to disturb him/her when you wanna go to the bathroom or kitchen. And yes, we had to pay extra 25 euro to sleep on separate beds with my friend, because the price given covers only that one kingsize bed.
Overall, we had good experience staying there. Recommended mostly for the interior design and good location if you need to be in a walking distance from the station.
