Overall this is an excellent place to stay, and we would definitely stay there again. It's a short drive not only to Sea World, but to a bunch of other attractions like the Zoo, Midway Museum, beaches, etc. There's a little Mexican place within short walking distance one way up the street, and coffee the other way. Everything in the house was comfortable, the appliances were up-to-date, and the kitchen was well supplied. We had no trouble at all checking in.
A couple of cautions:
First, the garage door is a bit narrow. We were in a Toyota Camry, and although it fit, we had to be careful. If you are in a really big vehicle you might end up parking in the driveway.
Second, the place is not too far away from some railroad tracks. I'm a light sleeper, and the train woke me up the first night. After that I slept through it.
