Location: This apt is in the Sallustiano area. Making it far enough from the madding crowds but close enough to be able to visit all the sights either via a longish walk or with public transportation. We preferred to be not surrounded by tourist trap/ripoff restaurants and shops and so this was a perfect location for our family.
Host: Fernando is a superhost for a reason. He met us at the main entrance and showed us around his house. He even showed us on the map, places to avoid and places to visit as well as the best gelato place in the city!! He marked all the main transit stops and lines. He had even gotten us a bowl of fruit and some pasta/sauce to make dinner. Plus coffee, tea, sugar, water and all other basic kitchen amenities! To top it all, he gave us a ride to the airport in his large car for the same price as a small taxi!
Apartment: It's on a higher floor, but not an issue as there is a small elevator if needed. There are 3 decent sized bedrooms and a large spacious, airy living area. (with a piano!!) The kitchen is full sized with all amenities. The bathroom is huge with a washer.
The a/c is only in the living area so if you are there in a hot spell like we were, it could be an issue. We did have a fan in the main bedroom so it wasn't an issue for us at night. The kids just moved to the living room when they got too hot.
We enjoyed staying in a mainly non-touristy area. We were able to sample local restaurants, shops, cafes and gelato spots without being worried about taken advantage of (Which we did experience in a restaurant closer to the Vatican!! :-( )
All in all, a great experience and great talking to Fernando!
