As a student on a one month practice at UNAM, I would recommend Edna's place because it has all the necessities a student needs. Fast and reliable internet, short distance to University, supermarkets and markets within 5 minut walking distance, nice bathroom, a washing machine and a dryer, tv with netflix for rainy days, pretty well equipped kitchen, etc. The place is also very safe, there are security working 24/7 at both entrances to the building complex. Nights are quiet so you can sleep good. Edna also has a tap in the kitchen that provides clean water that you can drink, so you don't have to worry to buy it in the store everyday. Rooms are clean, the cleaning lady comes every few days to change the sheets, take out garbage and clean the floor. Also, apartment is in the second floor, so you don't have to walk far with your things. The host is a very nice and communicative lady, she speaks English so there are no misunderstandings for foreigners. I would recommend this place not only for students but also for tourists on holidays. I am very satisfied with what I payed for, and I'm giving this place 5/5 stars.
