This is a beautiful apartment in Mexico City, one that I would live in myself. The two floors (bedroom and bathroom on the balcony level, and living room and kitchen on the bottom floor) makes the space feel very large. The huge window facing the street lets in beautiful light. It was also probably the best stocked Airbnb I've stayed in (nice extra blankets, iron, kitchen appliances, cleaning supplies, Netflix, etc). It's also super stylish.
I'd say the only downside, if there is one, is that it's location is in a quiet, plain neighborhood (it's not in the heart of Roma, or Condesa, or Polanco). Those neighborhoods are definitely walkable, and some might like the fact that it's a bit removed, but that's the only thing I'd be aware of. That being said, I'd stay here 100% on a next trip to CDMX.
