Marco's place is perfectly located in Roma Nte. The doormen were very helpful, the rooftop was a nice bonus, and Marco's hospitality was excellent. He checked us in, showed us the ropes, and was extremely welcoming. It's a terrific place with very comfortable beds.
The only caveat is the construction across the street can begin fairly early in the morning, but if you're an early riser, that won't be a problem.
