Staying at Marco's here was perfect. Can't hear anything from the room, but the street was always lively and fun. We would often even come home from centers of the city that all had gone to sleep to find ours still bustling with people eating and drinking at all the different restaurants on the street and ones around it. Piazza navona is right around the corner with three beautiful fountains and another ten or so restaurants. We saw multiple wedding photos being taken there :) we stayed for 11 nights and walked everywhere every day. Almost everything we wanted to get to was between a 2 and 20 minute walk away. Marco was very responsive and helpful (and kind!) any time we had any questions and pointed us into the right directions on the map. The only (minor) complaints we had was the garbage people ringing our doorbell in the mornings (I know all of rome is on some sort of complicated trash pick up schedule, so I think that might be unavoidable), and the shower was super tiny, about two square feet. He did say that was getting renovated to be bigger though so it sounds like soon enough it'll really be flawless! We would definitely come back and recommend this place to friends :)
