Excellent location if you are looking to be close to Trevi Fountain. A great co op at the end of the road where you can buy any supplies or food you might want. Also a decent distance to/from the metro station.
I unfortunately did not experience the best condition of the apartment. There are numerous things that need a bit of attention, e.g some damp in the kitchen, temperature tap on the shower was not working properly. It just needs some TLC in a few places.
I also wish I had noticed before I booked that there is absolutely no view or outside facing window (or window at all for that matter). It keeps the noise out, but I would have preferred some sort of outside air/ventilation. It is a very strange feeling coming back to the apartment after being so immersed in the city to then not have any form of outside window. But perhaps I need to do more research when I book apartments in the future.
