Casa Blanca B-104 was a perfect site for my first visit to Puerto Penasco. The hosts were super-responsive, the unit was immaculate upon arrival, and everything was just as described. The property overall shows some age (the water feature was not working, perhaps something seasonal as no one appeared to be working on it, many of the trees and bushes look less than healthy, etc.). Also, this property appears to be the site of a large Spring Break party zone at the beach (chairs and tables and lounges were helter-skelter, wholly unoccupied during my stay). The resort is super dog-friendly though and the unit accommodated us all without complaint.
