I cannot say enough good things about our stay in Claudia's apartment. She is indeed a "super" host, who left a delicious dolce on each night stand and also provided an array of fruit, snacks and homemade Limoncello for our enjoyment. There is also a "handbook" in the night stand containing neighborhood history and restaurant recommendations.
Claudia was very responsive and prompt to all communication, it could not have been easier.
The apartment was incredibly clean and the perfect size for relaxing after spending each day exploring the city. While it was not disturbing to us, the street can be a little noisy with the windows open but is quiet with them closed. It's location is right next door to the Jewish Quarter and is also extremely close to Campo de' Fiori, Trastavere, and Ancient Rome. Additionally, Vatican City is an easy walk of not more than 20-30 minutes. There is a bar (coffee shop) a few doors down, and all manner of bakeries and restaurants close by.
You can walk to the apartment from Termini in about 30-40 minutes depending on the time of day and your amount of luggage, though we arrived mid-day and found it a little hectic to navigate the sidewalks and cobblestone streets with our rolling suitcases while traversing some heavy pedestrian traffic. We opted to take the #64 bus back to Termini, with the closest bus stop being only 5 minutes from the apartment. Super easy and convenient.
Staying at this apartment and working with Claudia was a fabulous experience, I would recommend it to anyone, and would not hesitate to book it again if we find ourselves back in Rome.
