This is one of the best Airbnb experiences I have ever had and I cannot recommend this place enough.
First, in case it's not clear to anyone (it wasn't to me): this is basically an apartment building with a number of different units. Once when the cleaning staff was cleaning another unit, I peeked inside and saw that it was bigger than mine. Size may relate to price, but I'm not totally sure. I just mention this because what I experienced in my unit may not be the same as for everyone else. For example, noise level may depend on whether or not you are facing the street, etc.
Building security could not be tighter. The building entrance has two doors, one after another (you get one key for each door). Once inside, there is an elevator for those who need it.
My room was on the second floor and I faced an inner courtyard. Outside was basically a wall with barbed wire. My "view" was a brick wall about 15 feet across from my window, but I didn't visit Mexico City for a hotel room view. I value price, location, cleanliness and safety. If you need a spectacular view, pay more and go somewhere else.
After examining my unit, the windows and the walls outside, I felt so confident that no one was getting in my room that when I went out, I left the windows wide open with all my belongings inside my room. There is no way anyone was hopping over the barbed wire and then scaling dozens of feet of flat brick wall to get into my room.
My unit had two locks on the door with two different keys. To get in from the street outside, a person needs 4 separate keys. Like I said, the security is tight.
The management office is in the lobby. The two ladies who work in the office, Lorena and Maythe, could not have been kinder and more helpful. I stayed here for 10 days and they periodically dropped me a message to see if I needed anything. Once they even gave me advice on how to get to a local tourist attraction. Thank you, Lorena and Maythe!
The first thing I noticed when I entered my room is that it was spotlessly clean. No weird odor, and every surface was clean. There was tons of closet and drawer space, all immaculate. Even the insides of the drawers were clean (no dust, etc). There was a huge walk-in closet with about 10 hangers. The room itself was not especially large (maybe around 12 x 12 feet), but you get what you pay for: my total cost was about $14 USD per night. All the bedding smelled fresh and clean (no mildew odor) and even the mattress was clean and new.
My room had a bathroom with toilet and shower, and hot water 24/7. My room was absolutely dead quiet. Once in a while I heard a little chatter in the hallways outside, but it was rare. The room was extremely quiet.
Other reviews have mentioned poor internet access, but that wasn't a problem for me. My internet connection was strong and I even watched a few Netflix movies one night when I wanted a break from going out.
The housekeeper comes once or twice a week. She changed my bedsheets, gave me new towels, swept the floor, etc.
The block the building is on is nothing special (nothing scenic about the Metrobus station outside), but you are literally a 5-10 minute walk from some of the most beautiful areas of Mexico City, including Condesa, Roma, and Hipódromo. I walked to the beautiful Parques México and España almost every day. There is a charming cafe one block away called Quietude. Great cappuccinos. You are also like 2 blocks from the Metrobus Line 1, which I found to be my most often used transport line, since it runs for miles north to south along Avenida Insurgentes.
The only thing about my room that wasn't perfect is that the window curtains are quite thin, so the morning sunlight enters the room as soon as the sun comes up. If you're an early riser, that's fine, but if you ever want to sleep in one day you're going to have a lot of sunlight in the room in the morning. If this is an issue for you, I recommend bringing an eye mask. If you need to buy one nearby, check out the store called Miniso nearby. They sell eye covers.
If you want luxury and fancy amenities, go somewhere else. But if you want a clean, quiet, safe, centrally-located place at a good price with an excellent, helpful staff, come here. I would come back in a heartbeat!
