We loved the apartment. It was very easy to walk to the Piazza del Popolo and we ended up walking pretty much the whole time. The breakfast room is very cute and everything was spotlessly clean! We didn't meet Paolo but only his mother who was very welcoming. We didn't see any of the other guests - we did hear them sometimes in the morning getting ready but didn't mind it. Also we didn't hear much noise from the street at night time and slept very well. Definitely a recommendation.
