I had an okay stay however one thing I've learned after 3 AirBnB experiences in Mexico City is to book for one night only and extend your stay after so that you can actually see the place, meet the people, and get a sense of the atmosphere first. I think this place would have been perfect for a short touristy stay but was probably not appropriate for what I needed at the time and I have to take the blame for not doing my due diligence.
Here's what I liked: the building is located in a very central location and there are plenty of places within walking distance. The bathroom window doesn't close so in the winter it is always cold there BUT the water gets really hot so there is some relief. The room is spacious with a decent bed and gets some sunlight. Also, the girls are willing to answer all questions and seemed friendly.
Here's what didn't work for me but might be totally fine for some travelers: the girls have guests over fairly often who also stay the night. On the plus side their guests seemed friendly enough and if you vibe with them you might actually make a new friend or two but on the negative side you never know who/what you're coming home/waking up to and occasionally you might be woken up on a random Tuesday night by music, talking, and smoking. I prefer a serene environment at home, but if you're a guest who loves that kind of thing this is definitely your place.
Also, travelers from the US should note that heating requirements for apartments do not exist in Mexico City. Temps can drop to 30s at night (by comparison apartments in NYC are required by law to maintain a minimum temp of 65. Most nights I had to sleep with my jacket on and 3 pairs of socks and I was still cold. If you're coming in the winter ask ahead if your host has or is willing to provide a space heater (my next place did and it's kind of amazing how much happier I am). A simple thing like being able to take your coat off when you come "home" really can make all the difference in the world.
So, yeah I know this review is way different than the previous ones that rave about their stay here but it's what I wish someone had written before I booked in for 3 cold, long, semi-uncomfortable weeks. I can think of one friend whom I would definitely recommend this place to because it's totally their style---it's just not mine. Read all of the reviews, give this place a shot for a night or two and make up your own mind :).
