I stayed at Sergio’s place for a month and it was great for a long term stay. It was comfortable enough for two people with a well equipped kitchen and a little desk and chair for working. I was able to teach online with the wifi with no problems. The neighborhood is fantastic authentic Mexican with the more touristy Condesa and Roma within walking distance. There were lots of places to eat and buy fruit and vegetables as well as a lavandería and convenience stores all nearby. I felt very safe and everyone was very kind. I highly recommend just for the location. The only issue we had was one horrible night where one of the neighbors played music so loud it vibrated all of the furniture until 5am. Unfortunately Sergio couldn’t do much about it but was attentive to what was happening. I hope things can work out so it’s not a problem for the next guests.
