The host was responsive and helpful with using the combo washer/dryer. Entering the apartment was easy.
The 1st floor (2nd floor in US) apartment was great for a 10-day stay in the Cuauhtémoc neighborhood of Mexico City. The apartment is 1.5 blocks from Paseo La Reforma on Calle Rio Guadalquivir. There was always a helpful & friendly security guard in the lobby.
The location was superb. There are bars and so many restaurants within a 5 minute walk. There is a small market about 4 blocks away and there is a Walmart Express about 10-15 minute walk away. I was able to walk to nearby neighborhoods of Roma Norte and Condesa. We got everywhere we needed to go using Uber. In the neighborhood of Cuauhtémoc, this location worked perfectly for us.
The 1 bedroom apartment was very well appointed. Large TV with many streaming apps was great. Excellent Internet speeds. Appliances were modern, including a combo washer/dryer. Kitchen was well stocked although I decided not to cook because the sink was very small, so washing dishes would have been a little difficult. Plenty of towels in the bathroom and kitchen.

Mexico City is a big busy city, so there will always be some noise. I tried to pick a "quiet" street for my AirBnB stay. Even though the apartment faces the back of the apartment building, there is some noise at night from other nearby apartment buildings.
The primary issue we had was that it was unusually hot in CDMX during our stay. The apartment would heat up during the day and we did not want to leave the windows open when we left the apartment, since we were on a low floor. We would only open the windows while in the apartment, but then we got A LOT of mosquitos in the apartment. I ended up with almost 2 dozen mosquito bites while sleeping, as did my wife. Ideally, a window screen would have been a big help, although this may not be possible with these windows, not sure. Of course the hot weather was nobody's fault and apparently, air conditioners are not common in CDMX.
Overall, I recommend this apartment, for it's great location and its many amenities such as appliances, large TV and Internet speeds.
