My parents and I stayed in this beautiful appartment for 4 nights and it was the best location we could have asked for. Walking distance to pretty much everything, loads of cafes and restaurants around the corner, and the best baked goods shop in front of the door (the smell in the morning... yum). The appartment is newly renovated in a very cool style, great mix between traditional and modern. It was spotlessly clean, very spacious, I guess the only minor downside is, it is a little noisy on weekend nights, so bring earplugs.
Maurizio and Fabio provided everything we could have asked for and always answered text messages within minutes. So we would definitely stay here again next time we want to visit Rome.
