Our stay in Monia and Gian Luca apartment was perfect. We stayed in their apartment for 6 weeks and everything worked perfectly.. the dishwasher is a great plus!
The communication was also great.. they answered immediately every time we needed them.
An last but not least, the location is also ideal.. the tram is a few steps from the building (which takes you directly to the main touristic places: Altar de la patria, Roman forum, coliseum, in less than 25-30mins), 200 mts from trastevere station, and 20 mins walking to the center of trastevere.
