I spent two wonderful weeks in this apartment in April of 2022, and I will honestly say that this is a super place to stay in Rome. For once, everything is exactly as the pictures show, and the hosts are super responsive with any questions or issues.
The galley kitchen is sleek and elegant (tip: the light switch is outside the door on the right near the window.) It contains a clothes washer and a dishwasher. (There is no dryer, which concerned me, but there is a drying rack in the bathroom that works perfectly for small loads.)
The bathroom is modern and luxurious. Revel in the rain shower.
The sitting room is huge with 14' beamed wooden ceilings (the building is 16th century)
The bedroom is also large with a very comfortable bed that came with pressed sheets, a real luxury.
The windows face an inner courtyard, which some might find a little dull. Trust me, in Rome, this is a luxury because the streets are very loud at night. The apartment is totally quiet and I slept perfectly every night.
In terms of location, you couldn't be better situated: almost on the banks of the Tiber next to the Piazza Navona. The Vatican is a 20 minute walk, the Pantheon and Trevi Fountain 10; the Forum 25. Cabs are everywhere, but I recommend you walk because around every corner there is something to delight. There is a Carrefour grocery store about 3 minutes away as well, along with a whole host of restaurants. The one on the corner across from the Museo Altemps hosts great live music on the weekends.
A few quick tips on what to do. The Museo Altemps mentioned above is literally the next building over and has a fantastic collection of Roman and Renaissance art. It is never crowded, nor is the Palazzo Massimo, with its incredible displays of Roman wall paintings. Do plan a day visit to Ostia Antica (better than Pompeii and only 20 minutes away) and for some great fun take a guided food trip in Trastevere or a guided bike trip down the Appian Way (spectacular!)
I heartily, heartily recommend these accommodations. I hope you enjoy them as much as I did.
