Lorenzo is a great host! He answered all question ASAP.
Appartment is also great. They locates not so far from center and its possible to access it by many trams and busses (around 15 minutes to Coleseum).
Moreover, this Area is also cool. There are no thousands of tourist but a lot of cafees and local market. There is everything needed in the kitchen to cook something local and fresh.
Also, I would like reccomend the vinotec just in the neighbour building.
The next time in Rome hope to stay here.
