I stayed for a month at Paula's and Miguel's Airbnb -- it's a cute studio-style apartment on the third floor above the main residence. I felt really safe up there knowing that the family was downstairs and that there were two locked doors between the residence and the main street. The panoramic sliding windows at the front and back were a great touch and made the apartment feel so open, especially while I was working from home and the main room and bedroom are very spacious. Even at night it felt very private because there are a lot of trees giving some privacy and the building behind is a school, so it was very quiet (especially by Mexico City standards!) and private. Since it was late May-June and the first part of the month was unusually warm, I slept with the slider in the bedroom cracked open and a fan they gave me. Once temperatures returned to normal (cooler nights) I didn't even need the fan.
The kitchen came stocked with pots, pans, cooking utensils, and dishes, including an espresso kettle and a French press, so it was easy to make coffee and cook light meals for myself. The market and main square in Coyoacan is a short walk away, and it was nice to be able to easily access the main attractions but also be a little bit away from all the people and noise. One reviewer mentioned the dogs barking - that was somewhat sporadic and to be expected in Mexico City. I honestly didn't think it was an issue, even while I was working at home. Any barking was typically a dog down the road and the hosts' dogs only barked when they saw someone come in through the courtyard gate (so no one is going to sneak up on you!). The little dog, Poochito, was very friendly and sweet and would calmly greet me with a wagging tail when I would come back, which was really cute.
Miss Eutiquia came once a week to clean and do laundry -- she was very kind and I was grateful for her hard work. The bathroom shower had plenty of very hot water, even when my friend visited for a weekend (which the hosts kindly agreed to), and it had no weird smells or anything (a different airbnb I stayed in up north had some issues with sewer smells - but Paula's airbnb was renovated really well and I had no problems with that!). There isn't a TV, but I honestly didn't mind and just used my laptop for that if I wanted to.
Because windows don't typically have screens in Mexico City (unlike the US) I did have the occasional mosquito or moth fly in at night, but that wasn't a big issue -- the hosts left a repellent plug-in for the mosquitos and I only used that occasionally after it had rained because I tend to get bit a lot. The only issue I had was occasional ants coming in from the neighbor's front patio after it rained after being dry for awhile. I texted the hosts and they were very responsive and gave me poison to put out that really helped.
I would 100% stay here again. My stay was smooth and comfortable, and the hosts are great. I love the area and it was really easy to walk around and access great restaurants and markets.
