The apartment is very nice, it's clean and it has everything a traveler needs for a vacation.
The place has more than enough room for a couple, the kitchen is fully equipped with everything you'll need and more, there's hot water in the shower every hour of the day.
The bed is very comfortable and there's AC over it as well.
The apartment is on the 4th floor with no elevator which might be a little irritating(espcially with the luggage), location is a bit far from the center of Rome, but it's still a 5-6 minutes walk from bus and tram stations.
Mario was very helpful with everything we needed, we got locked outside without the key once and Mario quickly gave us a spare key.
