The location is beautiful. We really enjoyed the big villa, especially access to the golf cart.
Some unforeseen challenges including locking the door/security, Internet, and the structure in the far bathroom. The lock on the front door was impossible to close from the outside with a key. Because of fear of breaking the key, we used the balcony to get in and out. The neighborhood seems safe enough, but we were nervous when leaving our laptops and valuables in an unlocked home.
The Internet was a constant struggle. Because we didn't have good cellphone reception, we hoped that the Internet would be steady. Specifically when trying to reach Chela, the house manager, we were unable to discuss the door locking issues. Finally, the bathroom in the far bedroom was almost dangerous. The railing and curtain rod both collapsed while in shower and exiting the bath.
All in all, we had a great trip. Hamilton Cove is a bit distant from all the tourism in the center, but a great taste of Catalina.
