Alessandro is a super-friendly guy, he picked us up in the city center when we arrived and welcomed us with a coffee. Even if he was not at home the first days, he made sure we were comfortable during our stay, and was always available to give us some advice on what to see and to do in Edinburgh. His house is very well connected with the city center; there are always several buses and it takes around 15 minutes to get there, depending on traffic. So, overall, I'd definitely recommend to stay at Alessandro's! :)
