Our staying in Barberini MongaHouse was great!
The apartment is located in very good area, just 2 minutes from Barberini metro station and there is a bus stop just under the building and you can easily reach most of the important parts of the city.
The bathroom and the shower is perfect and the kitchen is over equipped; you will find what ever you need to cook there. Bedroom is a little bit small but the bed is very comfortable. The apartment is very clean and exactly the same as the pictures. Living room also is equipped by good multimedia devices (tv, x box, dvd player, ...) and if you are a piano lover, you can play with a very good one in living room.
We did not see Stefano but Claudia helped us a lot. She is very kind, helpful and always available.
I will definitely think about Barberini MongaHouse if I am going to rent an apartment in Rome in the future.
