Maria's place was in a great location, just a short walk from the main centre of Trastevere. It was a lovely, spacious apartment with everything we needed for our short stay. Maria was incredibly helpful and available - very very detailed check-in instructions, and texted us throughout our tip to see if we wanted to meet up with her.
The only issue was the bed - it was quite uncomfortable. The mattress probably needs replacing as it was sunken in the middle. This didn't matter so much for a two night trip, but was the only place the apartment wasn't perfect!
