I stayed at Federica and Franco’s Trastevere flat for four nights with two friends. The flat was incredibly well-equipped, and with up-to-date but classic decor that I like to call timeless classic. Ideal for one to three people with a comfortable trundle bed in the living room. The living room and kitchen were perfect places to relax after long days of sightseeing, as was the patio (although without sun exposure, it was a bit cold during our stay). Although we didn’t cook during our stay, the kitchen is equipped with whatever you might need for a multi course meal. A small but pleasurable detail was the fine quality of the dishes and glasses.
Federica and Franco are wife and husband, owners of the flat, but Federica does most of the management. She was incredibly kind, communicative, and welcoming for the duration of our stay. They have a thorough guidebook with everything you might need for a stay in Trastevere. They even have a selection of English tourist guidebooks for Rome and Italy.
As to the area surrounding the apartment in Trastevere, there are charming shops, neighborhood cats, friendly residents, and amazing restaurants and bars. There is plenty to do, but it is quiet enough to sleep well at night.
