We stayed almost 2 weeks in this apartment and it was truly the perfect Rome experience. Located in the heart of Rome (next to the Pantheon) and surrounded by great restaurants (try la ciambella or even Vini & Cucina Blasi) and the best coffee in Rome (Sant' Eustachio caffè) you will have find everything you need just around the corner.
The apartment itself is located on the top floor (beware of the stairs, they are long and narrow. ;) it has one bedroom and one sleeping couch in the living room (which to my surprise was a very comfortable bed!). Definitely enjoy the terrace with a drink and some music. And do not worry: the air condition is working perfectly! ;)
My highlight was Sarah, the colleague from Paolo: she constantly checked in on us and made sure that we had everything we need. She speaks perfect English and was always there when we needed her. Thank you!
