I spent a very nice week in Marco's apartment. It is indeed a very unusual place, with many unique features. And the best part has to be the location. You step out the door and you are surrounded by all kinds of options for eating and drinking. Piazza Navona is 3 minutes away and you get walk to virtually every landmark in central Rome.
Marco was a very nice host and provided vouchers to get breakfast every morning.

Just 2 things for guest to be aware of:
1. The light comes from a large skylight, so you really cannot darken the room once the sun comes up. If somebody liked to sleep longer, this could be a problem.
2. The bathroom is small, as Marco writes in his description. There is also no shower stall, so every time you take a shower, the bathroom floor gets largely wet. Not a big deal, but maybe something to be aware of.
