the communication was great, we had a warm welcome were they explained everything. The apartment is close to termini station, 10 minute walk, so you can visit all the attractions fast and cheap. I would advise to go with the metro, €1.50 for 100 minutes. The neighbourhood is great, lots of bars and restaurants (I would recommend Saltimbocca San Lorenze + I Fratelli). Because of this it can be a little noisy (only the weekends), but if you close the windows you won't hear it that much.
All in all we liked it.
