Our family of six spent three nights in Lorenzo's unit last week. As a first time visitor to Rome, I can say that this unit was fantastic! The location is amazing (steps to major sites, transit, etc, plus a grocery store located at the base of the building, and a cafe right across the street). The unit is so close to the Trevi fountain, that we were able to visit it morning, noon and night...made for some great pics when the crowds were smaller.
The unit is much larger than I thought it would be - it is very spacious, and nicely decorated. The two washrooms, washer and dryer, sleeping areas, etc are great for a larger group. There are piles of books about Rome in the unit, which were enjoyable to read. The balcony and balcony seating was fantastic - we sat outside frequently, and enjoyed seeing the herbs and other plants, and looking over the rooftops.
The kitchen is well appointed with all the basics. While we mainly used it for breakfast and night time snacks, it looked like every type of pot, dish, cup and utensil was available.
One thing to note is that the unit is on the 5th floor - so there are quite a few steps to walk up and down. The pitch of the stairs is gentle though, so it is not a bad climb. There is an elevator which we used for getting our luggage up and down, but it is quite tiny by comparison to elevators at home. This wasn't a huge issue, and the tradeoff of the terrific location and spacious unit more than made up for the stairs.
Lorenzo and his staff were all excellent. Lorenzo answered many questions for me, which I really appreciated. He was very accommodating, and very helpful. We had an excellent trip and I would highly recommend this unit. Thanks Lorenzo!
