Marco is a very nice host, always responded quick to all our questions. After we check in, he explained us in detail about where to visit in Rome and how to go there from the apartment. He also recommend us some good restaurants, very useful information:)
The apartment itself is well equipped, large space. But I think there might be a problem with sewer cause the bathroom and the kitchen area always smell kind of funny :(
One thing I have to mention is that the apartment is located in a local residence area, when we arrived there about 20:30 to 21:00 by night, all the shops around are closed and street seems quiet dark... and on the way from metro station to the apartment, we were followed by 3 young men with beers in their hands. It was quiet scary but thank god nothing happened.
