We spent three nights at Paola's and Gianmarco's place. The communication prior to the visit was clear and smooth. Upon arrival, we were met by Adrian, a friend of Gianmarco, who was very helpful and provided us with a lot of useful information (on top of one of the hosts'). Next day we met Gianmarco, and he was also very pleasant and friendly.
The apartment is located approx. 15-20 minutes by tram from Termini station and 10 minutes from the subway. It is situated in a very nice and vibrant (in the evenings) area. There're a few bars, of which Necci is the best :)
The place is neat, clean, and very nicely designed.
Thanks to the hosts for a great stay!
