Coyoacán is not a village, as I have read (it was once a separate town), but a large district (about five times larger than Polanco). Cecilia's house is at the eastern edge of Coyoacán; from here it's a pleasant 25-30-min walk to the "touristy" area of Coyoacán (around the Central Square and cathedral). Right near Cecilia's house there is a lovely park and the "Museum of Invasions" in an ex-convent, also in a park. The best part about this location is that the metro station (General Anaya) is just a few steps away. This metro line (#2, blue) takes you directly to the Zócalo, Bellas Artes, Hidalgo (transfer to the new double-decker line 7 of the metrobús that runs along the entire Paseo de la Reforma to Chapultepec Park), and San Cosmé (transfer to the bus to Polanco & Soumaya museum). In the other direction (south), the next station is Tasqueña, where you can take the Tren Ligero to Xotepingo (10-min walk to Anahuacalli Museum), or to La Noria (5-min walk to Dolores Olmedo museum). The 81 reviews of this Airbnb listing have all been extremely positive and it is true that Cecilia is a wonderful and very accommodating host (I only met one Cecilia) and you can certainly have an enjoyable time in this tiny studio apartment; however, no place is perfect and everyone understands that at a low budget price like this there are bound to be a few inconveniences. Many reviewers have said that the Wi-Fi is fast and reliable; I did not find this to be the case during my week stay here. Perhaps the Wi-Fi is just variable and I was unlucky, but on only on a few occasions did I measure 12-14 Mbps; most of the time the Wi-Fi speed was less than 1 Mbps. WhatsApp calls were choppy and difficult. Cecilia mentioned that most people don't plug in the refrigerator; now I understand why: the refrigerator works well but it has a low hum or whine that in the quiet of the night makes it difficult to sleep. I just turned it off at night. If you are an early riser, you will not have a problem with the loud PA announcements around 7-7:30 AM at the secondary school right next-door (otherwise, ear plugs help). There is no sink in the room and the bathroom sink is too small to wash dishes in; you have to use the small laundry tub located just outside your door in the courtyard which is used for parking a couple of cars (other people live at the back of the courtyard). Lots of extras are provided: in the kitchen, three types of oil, condiments, two coffee makers, and a new induction hotplate which works really well; in the bathroom, hand sanitizer, hand soap, bar soap, shampoo and conditioner. As one tall reviewer mentioned, a very tall person will not to be comfortable using the toilet. There is no room for a shower curtain, so that when you take a shower, the whole bathroom gets wet. If you want to use the sink or toilet after you shower, you will get your feet wet again. It's been hot this week (29 deg. every day) and the room does stay quite warm at night. You can leave the one window and the door open, but there are no insect screens on either one. While I agree that the neighbourhood appears to be very safe, when I walked back from the centre of Coyoacán (where all the action is) at 11 PM on a Saturday night, after walking a block or two from the Central Square, for the rest of my 30 minute walk I was alone and the streets were almost completely deserted. A woman walking alone might feel uncomfortable; however, a Taxi or Uber will cost only $2-3 dollars. All of these inconveniences are not major problems but I just think that after so many extremely positive reviews, some people may be a little disappointed in the reality. All in all, I enjoyed my stay.
