Marco's apartment was perfectly located for my work in Rome. Right off the Piazza Risorgimento, it is connected via Tram, bus and metro to most places in the city. The apartment is well equipped and incredibly spacious for a place in Rome. The beds were very comfortable and the there was plenty of storage.
I wasn't there to meet Marco, but my friend who arrived first and left last told me that Marco was incredibly accommodating, friendly and helpful. When we need something for the kitchen (a cheese grater), he made sure that he had it within a day. Marco was a great and very responsive host, and I will definitely want to stay at his apartment again.
