I lived in the apartment for five weeks, learning Spanish at a nearby school.
Amazing location, truly right in the heart of Roma, which IMO is the neighbourhood you want to live in as a tourist for sure. All the cool cafes/bars/restaurants/galleries/picturesque plazas/tree-lined streets your heart could desire. The apartment itself is as advertised, no surprises - basic but comfortable, clean, and functional. Super comfortable bed with tons of pillows, a very rare thing for Mexican AirBnBs in my experience.
Nina is an excellent and responsive host. She even brought extra bedding for a guest I had.
The one thing to be aware of is that it is quite a noisy building. Not Nina’s fault, but if you are a light sleeper like me, it can be an issue, I was earplugging every night for sure. That being said, I had two guests and they had no problems sleeping at all. So this point is really just for other restless folks like me.
Oh ya and also, like most apartments in Roma/Condesa, it’s a walk-up w/ no elevator, so make sure you can handle the stairs.
