We spent 5 nights in Paolo and Daniele' s place and it was all great. The location is excellent, within walking distance of restaurants and cafes, and also the major attractions of Rome. The communication was very good, Paolo helped us with everything we needed at check-in, and with a possibility to store our luggage for the check out day. The apartment has all you need for this kind of stay, especially when you use it mostly on early mornings and late evenings. The only small downside was the noise outside, as it is a neighbourhood full of tourists and busy nightlife.
Otherwise, it gets two thumbs up from us.
