I stayed at Lorenzo's place with one friend of mine. For us it was perfectly located, and it's only few minutes walk to the city center. The place has all amenities that we needed and more, especially liked the shower with the rain forest head. Lorenzo was really helpful and always replied quickly to any of our questions. He even picked us up from the airport and gave us a quick "tour" through the city at night on the way back.
The only negative things I'd point out were that the apartment was quite humid which made it feel slightly uncomfortable at night and there were construction works going on in the building, which hopefully will be done soon.
Thank you for a great stay, Lorenzo!
