Highly recommend! Comfortable apartment, convenient location, very responsive hosts!
We stayed here for about 4 weeks and had a very positive experience. The beautiful apartment is newly refinished and very well-equipped; it was also very clean and had a cleaning service for longer stays. The bed was very comfortable and there was plenty of storage. We also really appreciated having a washing machine (being a basement, things take a bit longer to dry, but as long as you plan, that's not a problem).
Trastevere is a really cool part of Rome, and I'm glad we chose this neighborhood! The area near the apartment is conveniently located for getting to other parts of the city, but it is a busier area of Trastevere for tourists and locals coming to take advantage of the many great restaurants (still not as busy as many parts of Rome). People were extremely friendly and we really enjoyed the feel of the area. I'd highly recommend going to Bar del Cinque, Il Duca (restaurant), and walking along Vicolo del Cedro - a picturesque and quiet street nearby with a communal garden and stairs to climb the Gianicolo (beautiful!). If you like music, photography, and local history, stop by Mohssen's antique instrument restoration shop along the way!
A note about noise (because I'm fussy about that, and noise was mentioned in another review) - this is a generally quiet apartment with some "white noise" sounds for most of the day and night.
The apartment is in the back of a pretty quiet building in general, even though the street is busy. There is a restaurant kitchen that shares a wall with this apartment - so the main noises you'll hear, from about 10:30-after midnight every day, are some sounds related to cooking (some machine noise, plates clattering, etc.). When I read the review that mentioned restaurant noise, I thought it might have been bursts of conversations from noisy diners, which I would have found harder to ignore, especially when sleeping. The actual sounds were mostly like white noise to me and very non-bothersome -- though I would recommend a white noise machine/phone app for sleeping, if you're concerned.
If you're interested in language learning, Scuola Leonarda da Vinci is about a 30-minute walk from here and offers language study for as short as one week (they also have many long-term students). We had a good experience there, and even though most people in touristy areas of Rome speak English, it's always beneficial and fun to learn the local language!
