This an excellent property - one of the best we have ever stayed in for the price. Great value.
Location: Fantastic. Close to Piazza Navona, Campo Dei Fiori, Pantheon, and Vatican. 25-30 minute walk to Piazza di Spagna or Trevi Fountain. Great restaurants nearby.
Host: World-class. Our flight was delayed by 5 hours and Antonello met us in the middle of the night and was incredibly gracious. His communication is superb - he's extremely responsive. Couldn't ask for more.
Apartment: It is impressively quiet and maintained cool temperature (even when it was 95 degrees outside). Bedroom is lovely, bed is comfortable. Bathroom is remodeled and large - nicer than what you would find in most Italian hotels, in my experience. Living room/kitchen area is simple - dining table for four, key appliances, well-stocked with housewares, and sofa with large TV. Clearly professionally cleaned. Includes wifi, which works well in living room and bedroom. Cell signal was not great, but doesn't matter because you have wifi.
Considerations: It is one floor above the street, so you need to take your luggage up a narrow staircase (but Antonello happily helped!). Not near a subway station, but key attractions were easily walkable, and taxis came quickly when called via the Italian taxi apps (not Uber).
Overall, we were thrilled with the property and the host, and it was one of the highlights of our trip to Rome.
