The apartment looks amazing and is even better in person. It is worth every penny and Muzio is truly a great host, always with clear instructions and very quick to respond and provide any clarification for our doubts. We had a bit of a late check-in at night, and that was no problem at all - the whole self check-in process was really easy and the host gives all the information you need, with pictures and maps even. As for the location, it is incredibly close to Fontana di Trevi, which means there are lots of things to see, buy and eat around just by walking, although it might be wise to go just a few blocks further to avoid some tourist traps, since the area has a non-stop influx of people wanting to see the fountain.
