Why at check-in time me they ask for an additional payment, in addition to the one that I had already made? I had already paid 227 dolars!!! The person who made the check in (is not Matteo) asked me to pay 3.5 euros per night and per person (in the ad never say this payment is required). Then if you're going to take this apartment you must know that additional payment. About the apartment, this is well located and nice.
From there you can get easy to most of the touristic sites and there are many restaurants around. The apartment has what you need to stay a few days in Rome. I didn't like the arrival at the entrance to the apartment because it is a dark and lonely alley and there are two trash cans at the door of the apartment.
