The room is OK, clean, neat, and well equipped, with private bathroom, TV and A. C. Breakfast is served in the bar across the street, which is also OK, a hot beverage and one pastry.
The location of the apartment is relatively fine, around 600 meters from Termini station and 400 meters of the nearest Metro station so you can move around easy enough, although walking a bit.
Unfortunately we did not have much contact with Luca. In fact, we contacted him 24hs prior to our check-out asking him if we could leave our luggage somewhere inside the building, due to the fact that our plane was leaving late in the night and it could have been very useful to leave the bags somewhere while we did some sightseeing our last day. Of course he does not have the obligation of providing such a space to leave the luggage, but what was most disappointing is that he did not even answer our message sent via AirBNB. Instead, we went to Termini station and paid around 30 euros for the luggage-keeping service. As I said, he was not obliged to provide the space, but an answer would have been nice.
Also, it had never happened to us that renting via AirBNB, we were charged the city tax. We used this system to stay in other Italian cities (which also charge the tax in hotels, for example) but we were never charged the tax. We never received an invoice or something of the sort either, but well, just mentioning.
