I stayed in Alba's place for three nights. It was first time with airbnb so I was a little afraid. Now my fears seems ridiculous to me. The room was very clean, comfortable and located in a good, quiet neighborhood. Her apartment is very close to the centre and I was able to walk to the Duomo and everywhere else I needed to go during my stay. Alba provided a detailed and clear email for me to find the route. She is also very nice and supportive host. I strongly recommend her place.
