Cathy is a very quick response, well communication and helpful host.
The area is a little bit "old fashion" but the interior of Cathy's house is perfect clean and new :-)
The location is almost in the center of all places my son wants to visit (Zoo, Safari, Sea World, USS Midway, etc.).
There is a coffee maker but fillter paper and coffee, bring it in if you are coffee lover ;)
In general this is a safe and good place to stay in SD.
Enjoy your trip!
