We had a great stay at Franco's place. He perfectly arranged his mother in law to hand us the keys and we really liked the flat. It would have been big enough for four people, even if we were only two. It's located in the centre of the city, only minutes walks from nice bars and restaurants. Still, it's very quiet and has a nice backyard for breakfast outside. Would definitely recommend Franco's place!
PS: Just don't rely on the restaurant tipps, we had the impression his mother in law told us more of the tourist ones - better go exploring yourself ;-)
