Silvia is a very friendly host. The apartment is very nice, the location was perfect for me(it's very close to a metro station, so you can reach the Duomo in 15-20 minutes tops) and I certainly would choose to return.
Sadly I didn't get to talk to Silvia more as I was away during the whole day, but she was very prompt at responding to messages and gave perfect directions. Also I enjoyed the company of Anja, a lovely cat who seems to be the real owner of the apartment :)
