I will start with the location - GREAT! The apartment building is located in the Lazio district. It is just a short walk to the Vatican and, if your a walker, a 45-60 minute walk to the Colosseum and all the other big sites; Trevi, Piazza Navona, Pantheon, etc. are in between.
The apartment itself was very well kept and tidy. We were three couples, all over 50, in our group and we had a good amount of room in each of our bedrooms. We did not use the kitchen once, but it was well stocked with pots and pans and coffee maker. But who needs a coffee pot when Pasticceria Riekkomi is right next door!
Valentina our host was very responsive to any questions that came up and check-in was a breeze!
