Marco is quite simply an amazing host, kind and helpful, truly the reason we use a service like Air BnB. The flat is as advertised, with comfortable beds and plenty of cooking equipment. Its main selling point is its proximity to the best of Rome without the insanity of the Centro Storico (though you are only a 20 minute walk to the Trevi). The Celio neighborhood is mostly Roman, not tourists, and there are a number of high-quality little restaurants in the area (most of which Marco will point you to). Its in the process of gentrifying and is very safe. You can easily spend 2 days just in the area of Celio itself to sightsee. And who doesn't want to wake up and see the Colosseum every morning? Also, Marco's apartment building has an accessible rooftop, which we used to watch the New Year's Eve fireworks. Amazing. The apartment is on the ground floor and across the street from a dive bar, so some nights can get a little noisy; if you are a night owl or a heavy sleeper you won't notice. You won't notice it much anyway - I think the only reason we did was our terrible jet lag. The apartment as noted is very nice, but it does need a little TLC. Our shower did not work very well when we were there (poor water pressure) - not due to Marco but due to the age of the building. Building management was working on the problem, but did not fix it while we were there; Marco then gave us a small refund due to the inconvenience. We highly recommend Marco and his flat - when we come back to Rome we would definitely stay here again. He loves Rome and wants to make sure you do to. And be sure to arrange a private cooking lesson - we learned how to make real Italian pasta on our last night.
