This apartment is fantastic, much bigger then we imagined. Clean, plenty of room and amenities, and best of all a beautiful terrace to relax on at the end of your day. The host was very prompt and readily available on airbnb and/or whatsapp and answered any questions and had plenty of suggestions. The location was superb for our 3 person family. Plenty of authentic food in the area and not just tourist stuff. (Definitely try Trapizzino and suppli while you're out walking around) The bakery below the apartment had fantastic pizza and pasta for a quick easy bite and Angelo's or La Vittoria were great for a sit-down meal in the area. (Also uber eats or Glovo were great for lazy nights.)The vatican is literally a 5 minute walk away and the piazza Navonna is about a 30 minute walk, Trevi fountain is about 45. Bus transportation is right by the Vatican or you can use taxi/Uber. FYI if you use uber it's a set price (b/w 7-15 each way) but if you use a taxi and pay in cash it's a more negotiable price.
Overall, 10/10 would stay again.
