I felt very comfortable and safe at Alejandro's place. The place is close to Parque de Mexico, restaurants, coffee places, a supermarket. Despite being in such a lively area, the room was super quiet at night, so I slept very well. The internet was fast and reliable, which was great to have chats with my family, and for the days I needed to have meetings on line.
If you love good coffee and stay at this place, I recommend "Blend Station", which is about a block away. The food there is also very good :)
Finally, if you love dogs and cats (which I do) don't forget to visit Parque de Mexico on Sunday. They bring many cats and dogs for adoption, and even if you cannot adopt them, you may take the dogs for a walk and give a donation to help keep these companion animals healthy until somebody can adopt them :)
