Lorenzo is truly a super host, A+++++. We originally had another reservation in Rome, and our host cancelled on us. I had difficulty making a new reservation, and Lorenzo guided me through the process with great care and patience. He let us drop our bags at the apartment early and was there waiting for us at the agreed upon time. He had water and tour books waiting. There were other nice touches that we realized later too, such as two umbrellas in the wardrobe and breakfast snacks.
The apartment is tiny, but perfect for those who planned to be out and about in the city. The location is great! It was a 3 minute walk to the Colosseum. The neighborhood is nice too. Everything was clean, and there is a lift. The apartment is on the first floor (up one flight of stairs).
