We had a wonderful stay in Marco's place. Everything was as described and the location was absolutely excellent. Close enough for public transit to all the big attractions but far enough away to not feel "touristy." Its also a short walk to a near by mall, which for us was a life saver as the airline lost our bags and we had to find somewhere to buy clothes (H&M IS IN THIS MALL!!, truly helpful if you need clothes for all ages). Several local eateries were great....highly recommend Sakura Ramen which was walking distance. We also lucked out and had a christmas market pop up across the street in the middle of our stay!
Marco was also accommodating when our itinerary changed (several times) and we were able to add on a few days with no hassle. I'd definitely stay here again when we end up back in Rome.
