Lorenzo was very understandable on our arrival (we were in a hurry as we had to go leave our car at the rental of the airport) and helped us with the luggages up the 4 flights of stairs to his lovely flat on top of doing a speedy introduction to everything we needed to know.
Location is great although a bit noisy at night if you don't have earplugs and you have a light sleep. It's a quick walk along the river to go anywhere and the way back is even more appreciable when the sun is setting.
