I stayed two nights at Mario's apartment. He was very nice, kind and communicative and he answered the doubts and questions I had before I got there. I could actually meet him on my arrival and, since he had some free time, we went outside and he showed me some good spots of the city and recommended me some other places to go. I believe that you really get to know a city when you see it through the eyes of a local, so I'm really thankful for that.
About the apartment, I felt just like home. It's very central, it was clean and very cozy. I had everything I needed in order to have a comfortable stay, I couldn't have asked for more.
I would definitely recommend!
