The place was clean, and exactly as described in the listing. The host was there to check us in, and show us around the place. They were also responsive in answering messages. The place was in a great location that felt save, and was very walkable. There were many interesting restaurants and places you could get to just by walking a few blocks. Outside of walking it's in convenient central location to take a taxi to all the interesting attractions.
The biggest con was the lack of air conditioning, but cracking the window a bit was enough to let the breeze in and keep things cool. We were there in May which is usually the hottest month, and things were comfortable. One of the bedrooms didn't have windows and it was more uncomfortable sleeping there at night because it didn't have the benefit of the breeze. The host had some fans provided in the unit to help with that though. If you were there during a heat wave I could see things being uncomfortable. Bring some bug spray to deter mosquitos from coming in the windows.
For more good stuff. The Wi-Fi was fast and reliable. The kitchen was fully stocked with dishes and cooking supplies. It was also convenient having a washer and dryer in the unit. The place also had a big private patio that was nice to hang out in. The unit is in an apartment building with a doorman. So when coming and going things felt secure and safe. Overall the place was a good value, and a great central location to see what Mexico City has to offer.
