We travelled to Cabo San Lucas with our 2 boys: 4.5 and 1 year old, our friends with their 1 year old and our au pair. Everyone had privacy in the home, and after moving up some breakables, it was reasonably toddler-proofed.
La Casa Benedica is probably the best-appointed rental home we've ever stayed in. From the real-home feel of the artwork and furnishings, to the kitchen gadgets and beach equipment that actually all worked, we all felt at home here for the week.
Cabovillas.com is the property management company and was very communicative through the whole process. We requested some baby gear and a dinner with butler service the first night and they more than delivered on both! (it took the entire week to finish the guac from this first night service). The concierge and the house keeping staff were attentive and had quick answers to our questions.
We will definitely come back!
