This was without a doubt the best airbnb I've ever stayed in.
The building itself had a 24/7 doorman, and we felt really safe and secure the entire time. Literally just downstairs are unlimited options of restaurants, bars, stores, etc. It was an amazing location in the middle of Condesa, which is a really beautiful, relaxing neighborhood in a trendy area of the city. The metro is a short walk away, and uber (which is cheap and reliable) will pick you up right outside the building. When you feel like ordering food in via ubereats, let the doorman know when you arrive, include instructions in Spanish in the delivery instructions, and the delivery people will bring the food directly to your door which is super convenient.
The unit was both aesthetic and comfortable - it was clearly recently updated and was extremely clean. It had a comfortable bed for two people, a large sectional couch, two bathrooms which was super convenient, a kitchen with everything you'd need to cook and an American-sized fridge. I worked for part of my stay, and the wifi was perfect the entire time for zoom meetings. This is a great place to work remotely.
The balcony is not really usable for anything beyond a view from inside (it has a sliding door), and letting cool air in at night (no need for AC in Mexico City - it gets chilly at night!). It didn't feel structually safe (it shook when we walked on it), and there was loud construction happening across the street (which we were warned about in advance and was not a huge deal). So don't rent this for the balcony! Other than the construction, which was only during certain hours and will likely be finished soon, the unit was super quiet.
Elvia was friendly, communicative, and helpful - whenever we had a question or issue she responded very quickly with a solution or suggestion. I would for sure stay here again, and I will recommend it to friends.
