We enjoyed staying at Alejandra's place. The flat was larger than expected. Both bedrooms are nice and comfortable. There is everything needed in the kitchen to cook. The bathroom is nice as well and you will get anything you need. This is a safe building, the location is great (about a 10 minutes-walk to the metro) and with a lot of bars and restaurants around. If you are, like me, a light sleeper, bring earplugs if you want to sleep before 11pm, the street is busy and people are having fun every night. That's being said, it didn't spoil our stay and thanks to this place, Mexico DF was a very good start for our trip.
