Roberto was very kind to wait for me and my friends at his place when we arrived even though our train from Florence was a bit delayed. He gave a clear detailed information on how to get to his apartment. The apartment is very nice, just like the picture, and it is in a good location, just next to the bus stop so it is easy to go everywhere.
Roberto was also kind enough to let us keep our luggages at his place after checking out because we still wanted to explore the city without having to drag our luggages around, before leaving the city in the afternoon.
I recommend to stay at his place.
