We had a great time at Lorenzo's place. The house is very cosy, bohemian. Situated in a nice and friendly neighbourhood very close to Vatican, the Chapell, the San Pietro square, etc.. Indeed there are some stairs to climb, but you can call it "daily workout". Lorenzo is a great host. He was super responsive, he helped us with every detail, and gave us lots of suggestions about the city from transport to places we should see during our stay. Overall it was an amazing experience and we recommand both the host and the studio. :)
