Staying at Marco's place was great. I was in Rome for just over a month doing research for my dissertation and the location of Marco's flat was perfect. The flat is very close to the Piramide metro stop, which is not too far from the Termini intersection between the A and B lines. This allowed me to get around very easily to the archives I was visiting in the various corners of Rome. The flat itself was great too -- A/C, comfortable furnishings, and a kitchen stocked with everything you'll likely need for a short- to medium-length stay. I was worried that it might be a bit noisy since the building is on Via Ostiense, but the room I was in actually had its window on the other side of the building, which meant there was very little external noise. Finally, Marco himself was awesome. It was a pleasure getting to know him and when I return to Rome, I'll be sure to try to book with Marco first before looking someplace else.
