1. The location is fantastic. A beautiful art deco building. The entrance is on a charming pedestrian street. It is one minute by foot to the Allende metro station (blue line).
2. It was very very clean.
3. The apartment is very quiet. Silent.
4. The bed/mattress was superb. Very firm and even, without being hard. The bedding was great, too. Sleep is important.
5. Note that I checked in before the sun was up, and I was able to easily get the code into the lockbox, and get the four keys and quickly figure out what the four keys were for. It was not a big challenge.
6. Regarding the silence, the apartment is in the interior, perhaps against the next building, thus the silence, but don't expect great views out the windows. There's a lot of light through its big windows, and sky, but not street views. Basically, this explains the lack of any noise.
7. The price was great.
