Lorenzo's place is great! Exactly as on the pictures, large living room/kitchen with all the bits and bobs you need, cutlery, crockery, kitchen towels, etc. Big and comfy bed, extra blanket provided. Bathroom with great shower and hair dryer. The flat is in the quite residential area, about 10 min walk to Vatican, close to two metro stations, but we did not use any public transport, but walked everywhere, its about 30-35 min walk to all the attractions in the city center. There are few shops within 5-10 min walk from the flat, plus many restaurants, bars and cafes.
The communication was great, Lorenzo was always prompt with responses.
I would definitely recommend Lorenzo's place and would book it again when I am next in Rome.
