Maria's Trastevere spot was all the we could hope for and more. From the communication prior to check-in through checkout, we had zero problems with this place.
Best location for food; Trastevere is full of delicious, authentic food. We really enjoyed Da Enzo for pasta, Dar Poeta for pizza, and La Freschetta for an all around meal. Ai marmi pizza was good too. Try Supplí everywhere. You want the best porchetta sandwich in Trastevere, go to Norcineria Lacozzolli and get a panini de porchetta con pomodoro secco (porchetta sandwich w, sundried tomatoes)!
I recommend looking into the Trastevere Food Tour if food is your thing. We did it on day one and had all the knowledge we needed for great food around the city (and how to spot fake gelato (80% of the gelato is fake in Rome)).
Finally, the MyTaxi app was a great way to move about the city, works like Uber, but very reasonably priced and you can pay through the app and add tip if you desire. Uber is here in the city, however they are licensed Uber drivers only using fancier cars so it cost more than taxis.

Anyway, had a great stay in this location, I highly recommend.
