The location of this AirBnb is perfect! Right in the heart of Trastevere but not noisy at all - a little off the major roads and streets with a lot of the action, but easy walking distance. The host was incredible from start to finish. We were going to Rome to visit my daughter studying abroad and then going with her for a few days to Sicily, then coming back to Rome. He allowed us to book four nights, not consecutive (3 and then 1) and because there was no reservation in between, allowed us to keep our luggage and belongings that we didn't need to take to Sicily with us as well as take a key with us so we could come right back to the apartment when we returned. He arranged for a car service to get us from the airport to the apartment which was perfect and tried to arrange for when to get to our flight to Sicily but that didn't work out (though not the owner's fault at all and he was super apologetic). The owner was always quick to respond to questions.
The apartment was well equipped and served well for the three of us traveling. They left us wine and some water bottles upon our arrival (and again when we returned back from Sicily) and provided all necessary linens, shampoos, etc.
The ONLY reason small downside of this apartment (and frankly, I'm sure this is not super unusual in Rome and the the way the buildings are built) is that there is very little (to none) natural light that comes in. The apartment is VERY dark and you wake up having no idea what time it is. The apartment also is a little musty - probably due to the lack of outside airflow. But, this was just a minor thing, and, as I said, not terribly uncommon with all the interior courtyards and the way the buildings are built there, I'm sure.
Overall, I would highly recommend this place. Great host!
