This is a very very tiny apartment. This is something you need to keep in mind. There really is barely room for two people, and that only if they’re very close and intimate. It would be great for a single visitor. But that said, the space is nicely appointed, intelligently updated and the little patio (which you should consider to be more like 70%of the living room) is charming and comfy. The bed is also comfortable, although again, the tiny bedroom feels a bit cramped from the regular-size furniture stuffed in it. But there is room for your things and for you.
The section of Roma Norte where the apartment is located is know for amazing restaurants beautiful parks great galleries and lively nightlife just a couple of blocks from the apartment. It is just a few blocks from a central Metro station, and has a few convenience stores in its vicinity.
If you are okay with a very small space -about as tight as a converted school bus + a little patio- then this place is a clean charming & well-situated choice.
