We loved Bob's Carlsbad beach house! We were so close to the water that we kept the windows open at night so the surf could lull us to sleep. The house itself was laid out nicely, plenty of room for me, my wife, and our 11-y.o. twins (boy/girl).
Great location, too! Close to I-5, quick drive into San Diego and, of course, the zoo. 10 minute walk into downtown Carlsbad, with tons of restaurants, shops, etc. Grocery stores, gas stations, etc. at the Tamarack exit off of I-5, 10 min. east.
All in all, highly recommended. Hope to come back.
