We enjoyed our stay at Nicola's place -- he adds very nice touches that are unexpected such as a light breakfast and includes a detailed and comprehensive guide that he created for those who are staying a few days in Rome. He even lists restaurants that he recommends nearby the suggested sites. The home is located in between two affordable eateries right next door, which is very convenient! The neighborhood is very non-touristy so bring cash if you want to visit the nearby restaurants! It would help if you also learn some basic Italian to get around. The nearest train station is just two blocks away, so it was easy to get around.
The shared bathroom is nice and the room gets plenty of daylight. It gets a little bit noisy in the early morning and late evenings on weekends if you keep the window open, but the windows block out most of the noise when closed. This might be a common thing in Italy, but the windows do not have nets so we did have quite the mosquito problem despite being Autumn. Overall, our stay was very pleasant and we would book with Nicola again if we return.
