My family of 15, ranging from ages 5-83, loved this spacious apartment! There was so much room, we never felt like we were on top of eachother. The rooftop also allowed for quiet time. The bathrooms were a good size, too. We were able to walk to the colosseum and Trevi fountain, but they were long walks, and unfortunately it was so hot when we visited. Luckily the AC in the apartment kept us cool. There were many restaurants and cafes close by, a great location.
Just be aware the elevator only hold three people at a time, so getting our luggage up to the 4th floor took some time. We often walked down to the ground level and had many in our group able to walk up the 4 flights of stairs. They were manageable and not narrow. This isn’t a con, just a note. We would stay here again. Valeri, the host, was often in contact with us.
