We stayed at Marco's place for a week while visiting Rome for the first time. Pictures were exactly as described, and even better when we got there. While Marco was not able to meet us to give us our keys, he had a nice lady, Daniella, hand us our keys. She was super nice and despite her minimal English, she was able to provide us tips on sightseeing and even gave us a map which detailed the bus routes. Apartment was spacious and had all the amenities you could need. Metro is a few blocks away so that was convenient. There are a few restaurants surrounding the area and pizza shops if you ever get hungry! Everything was described in the posting.
The only issues we had were in the bathroom and the apartment floor. Sometimes, the toilets wouldn't flush all the way, so it took a couple of times. The sink doesn't drain right away either, so if you leave the water running, it can take awhile to drain. The shower can be glitchy here and there, such as temperature spikes, as in it can go from hot to cold and back real fast. Floors were a little dusty but overall the issues were pretty minimal where it didn't affect our stay too much.
Overall, we enjoyed our stay at Marco's place very much and will come back here again if we were to visit Rome. We recommend this place to others if you simply want to relax and have a pleasant stay. You'll have everything you need.
