We have been visiting Trastevere for several years and have stayed in many different Airbnbs. Marco's apartment is perhaps the nicest place we have had the pleasure of staying! It is quite spacious for two people, and updated with tasteful furniture and many excellent amenities (including a dishwasher!). There are A/C units in both the living room and the bed room, both of which function well (very important in the summer!). Location is excellent: right around the corner from Piazza di S. Cosimato, and a very short walk to the 8 tram. There is also an artisanal beer and wine shop just next door, from which we purchased many tasty beverages.
