I have been using Airbnb in many places in the world, including several cities in Japan, Cuba, Ireland, and the US. This is the first time I stayed in an Airbnb in Mexico City (I am Mexican but could not stay at home for a couple of days).
This is also the first time where I encounter an Airbnb that is a company, as in, there are a bunch of little apartments -pretty much identical- in the same building, that are explicitly to be rented. This is more an "aparthotel" than your typical Airbnb. This is not per se a bad thing, nevertheless, is worth having it into consideration when you book it.
The zone is Polanco, which is nice, but it was a little hard do find places to walk around that were not close to a major avenue (Polanco is a relatively large zone in Mexico City). The building itself is in a smaller street but easy to find, is an old place that is refurbished but works. At the entrance you have a couple of people that check who goes in an out, every time I got in, I was asked for my room number, feels pretty safe.
My floor had 4 “apartments”. Just looking at the pictures from the website you might think that the apartments are much bigger than what they really are. We (my little dog and I) stayed only for a couple of nights and the place was functional for sleeping, but not if you want to work or do more in such space. Bed comfortable, bed good. They are very, very clean. The terrace is OK, good views, but didn’t spend that much time there either. I didn´t use the gym but it looked that it had all the basic equipment that you would need.
One thing that I loved is how fast and efficient they were responding to all my messages, it is important to notice that I did have lots of questions and requests, and every time it didn’t take more than 10 minutes to get a reply. You don´t really know who is replying, but that is OK (a couple of times the person replying signed as “Alan”).
In general, I would say is good value.
