We stayed recently in this apartment for a week. As we were travelling by train from Paris we chose this apartment for its proximity to Porta Susa station and it was only five minutes walk from the station.
For the two of us the apartment was spacious with a large lounge/kitchen, bedroom and bathroom. Storage space in the bedroom was excellent and the kitchen was well equipped. Wi-Fi worked well. Barbara ,the owner, met us on time and explained how everything in the apartment worked , where we could shop etc. We felt that there could have been some written information left about appliances in the apartment . A visitors book with tips on where to eat etc would also have been very useful.
Despite being near the station, the area round the apartment was safe and well provided with shops, cafes and restaurants including the excellent gelateria Romano.
Overall, we thoroughly enjoyed our stay here and would recommend Turin as a city to visit.
