We stayed there for a week. Las Canitas is a great neighbourhood, and quiet. There are a lot of dogs in the building ( but lots everywhere in BA). We never met Maria but her assistant was pleasant and answered our queries promptly. Lots of grocery stores and good restaurants nearby. We did have three short power outages in the entire area at various times during our stay and that seemed typical. The design of the apartment was pretty good, with lots of light and a nice outlook on the polo grounds. The bathroom was small and awkward but serviceable and clean. The security and doormen were great. We would definitely stay there again as it was good value for the price.
