My daughter and I stayed here for a week prior to the start of her study-abroad program. The apartment was very spacious, very clean, and all the systems worked well (AC, washer, shower). The location was also excellent for us, as it was very close to my daughter's university and of course right in the heart of Trastevere with its wonderful nightlife, dining, shops. The place is roomy enough to offer privacy (the bedroom is set off from the living room, and the kitchen is on a different level), but is also conducive to gathering for meals/games, or watching shows. Our host Arianna was fantastic, from finding places to eat and shop, to her assistance with my taxi on my last day in Rome! The property is a short walk to Villa Farnesina and its Raphaelite frescoes; Piazza Trilussa or Piazza Santa Maria - great for street performances, lots of restaurants - and walking or biking distance to attractions like the Trevi fountain or the restaurants by the Portico d'Ottavia. Overall, a great home base for exploring the Eternal City!
* I just want to note that very big/tall people may find it challenging to take a shower. The shower head is only about 170 cm (67 inches) from the floor, and the main opening is ten inches wide. (There is another, wider door to the shower - next to the toilet - but the ceiling is lower at that point.) It was not an issue for my daughter or I, but if my husband (5'10") had been with us, he might have had an issue fitting into the shower stall. I have noted this to our host, so perhaps this will be remedied in future.
**The stairs inside the apartment have vertical bars on one side, which are quite widely spaced. I would suggest that this property is best for adults, or families with older kids (not toddlers). Guests with mobility issues (I'm thinking of my mom who has a bad knee) may find it challenging to negotiate the interior stairs since there is only a banister on one side. I would highly recommend communicating with the host if you have any questions - Arianna is very responsive and helpful!
