We were traveling as two couples and the apartment worked out perfectly. The unit was very clean, air conditioning worked well, wifi was good, and overall a very good stay. The unit is just off a very popular street in Trastevere. We could only hear a little bit of noise in the front bedroom and the back bedroom was absolutely quiet. This is the price of staying in a very popular area. My only caution is that this is a very old building, and as such the doorways are very low. I had to duck going into different rooms. They had installed padding to protect your heads, but thankfully never needed it. We would definitely stay here again.
