Our four-person family stayed three nights at The Artist's House and recommend it highly. The location is superb, immediately next to the Pantheon with a great view of the Piazza della Rotonda. It's a short walk to the Piazza Novona, Fontana de Trevi, and lots of good dining and shopping.
The hosts could not have been more helpful; they communicated well and were very helpful when we got there. Max was always available to answer our questions and provided some good information about medical locations when someone in our party got sick.
The apartment is very nice and modern, having been renovated in 2019 (we were told). At the front of the apartment is a large living room/dining room with plenty of seating and two large windows that let in a lot of light and provided a great view of Pantheon and piazza. Behind is the kitchen, then a hallway to two of the (good sized) bedrooms and a bath. At the back of the apartment is another in-suite bedroom. Although this the smallest of the bedrooms, it has a small balcony. Be aware that the apartment is accessed up two stories of a somewhat narrow spiral staircase. Not really a problem, except when lugging a lot of heavy suitcases.
A perfect place to stay in Rome for 4-6 people. We thoroughly enjoyed our time at our apartment in Rome, and we're sure you will to. Grazie and Caio.
