The Blue Whale apartment was a wonderful setting for our groups Mexico City adventure. We had two couples very comfortably staying at the apartment.
The front room was fairly loud with street noise but a set of earplugs fixed that easily enough!
The apartment is manned around the clock by really nice gentleman so we always felt very safe. Also, the apartment is located in a super cute neighborhood (Roma Norte) with great restaurants, bars, and little shops and is a short (15 minute) walk away from Insurgents metro station with great access to all parts of the city!!
