In general, we were very happy with our two-week stay at this apartment with our toddler. There were some things that were inconvenient or frustrated us, but Juan was impressively fast in his responses to our messages and efforts to address our requests or problems. For the price, any place is going to have its imperfections, and overall we were very happy we chose this apartment. We recommend the place and would consider staying there again, and I imagine it is comparable or better than other similarly priced apartments.
Getting into the specifics...
Positives:
We were very happily surprised to find a garrafón water dispenser with a lot of water already in the garrafón, though it wasn't mentioned in the listing. This made it easy for us to have the clean water we needed.
Good location, central to lots of places we wanted to go.
Our first morning there we noticed that there was no toaster, and the listing said there was one. Juan got us one that very same afternoon. Impressive.
We were there in August and the temperature in the apartment was always comfortable.
The place was very clean upon arrival and they provided some basic cleaning supplies for doing dishes and also cleaning the apartment (soap, sponge, broom, etc.). The washing machine worked fine and the dryer took a little while, but we appreciated both.
My wife and I didn't know how to start the gas oven, so someone from Juan's team came to show us how. It's not their fault that we didn't know how to do this, and we told them they didn't have to come, but this again shows the kind of attention Juan gives to his guests' needs.
The beds were comfortable and they had at least two kinds of pillows. I'm picky about my pillows and I was glad to find one I liked!
The large windows in the living space let in lots of natural light.
Negatives:
The main thing that could be improved is that there are many things listed as "amenities" in the description that were not available upon arrival. It may be that these things are available upon request (like the toaster that was delivered), but I think this should have been made more clear in the description. If you want the pack-n-play, game console, changing table, olive oil, etc., be sure to let Juan know in advance.
Another issue was the fact that the sliding door that leads to the balcony cannot be locked. It seems highly unlikely that anyone could make there way into the walled private parking lot and scale the building to get INTO the apartment, but we were a little bit concerned about our toddler finding her way OUT when we weren't looking. The railings on the balcony are horizontal, in effect making a ladder. We never opened the sliding doors, and she never realized they could open, but if you have small children it may be something to keep in mind.
The hot water was... unreliable. Usually we turned the hot water on and a minute or so later it would come out warm, then it would get cold for a couple of minutes, and then it would come on super hot and you could then turn the cold water on to get the temp you wanted. Usually it stayed hot from that time on. Sometimes, it didn't quite go like this. Not really sure what was going on, it appears to be a tankless water heater.
I think someone else complained about noise from the nearby roads, but that wasn't a problem for us. On the other hand, we did hear a lot of noise from people in the central hallway/foyer of the building. This usually didn't happen in the middle of the night, and would only last for a short time, but the noise in that area really carries through the building.
Other info:
Maybe a bit counterintuitively, the room with the glass walls is the darkest and quietest in the apartment (assuming your fellow guests aren't making noise).
Location is pretty good. Chapultepec station is within easy walking distance. From there, you can take the metro or the nearby "trolebús" number 2 to a lot of places. You can also walk to Paseo de la Reforma where the 7 metrobús is pretty convenient when going east and west. That's not to say there aren't places to go in walking distance! You'll find coffee shops, bakeries, and lots of kinds of restaurants all within a ten minute walk.
There's a Farmacia Similares just a couple of blocks away, and if you speak Spanish it's a great option for getting some non-emergency medical attention. Our daughter broke out in some minor hives at one point and we were able to walk there and see a doctor in less than 20 minutes. The consultation cost us about $2.50 (50 Mexican pesos). He prescribed some medicine and we were able to continue enjoying our time in the city.
*Lastly, if you're considering any properties in CDMX owned by "Mr. W" I highly recommend choosing one of Juan's properties or one from any other host instead. I'd be happy to share more about our experience if you send me a message.
