GREAT stay in Mexico City! Would absolutely recommend this apartment to anyone considering it. As many reviewers have mentioned, it is definitely loud - but we came prepared with ear plugs for sleeping so it wasn't an issue for us. La Condesa is a wonderful neighborhood to stay in, and though the apartment is right on the main freeway, it has incredible views of the castle and city, and just around the corner is great for walking, eating, bars, parks, etc!
Alejandra (Amelia's co-host) was extremely communicative, friendly over email, and sent us many local tips, which we really appreciated! She was also very responsive - for example, the hair dryer did not work and she had one sent to us that day. She also left us a few snacks and drinks in the refrigerator upon arrival. Check-in and check-out were really easy, and we felt safe being in a building with a doorman.
I packed my own shampoo, conditioner, body wash, and lotion - but one thing to note, there was just one bottle of shampoo/conditioner combo and none of the other things, so plan to pack your own.
We had an amazing time in Mexico City, and this great apartment definitely contributed to what made it so perfect. Would highly recommend staying here!
