We wife and I stayed at this house for five days in January and had a great time (even though it rained and was cold most of the week!).
The house is as large, beautiful, and clean as advertised, and the outdoor space is great. I'm very noise sensitive and wondered a little bit about a house on a major road, but it's extremely quiet. It's set well back from the road.
As other reviewers have mentioned, Larry is great. He's the perfect blend of being serious and available when needed, but also laid back and very respectful of privacy when not. He was nice about letting us change our schedule a bit, helpful when our car had a tire issue and we didn't advice on where to go, and just generally very pleasant to work with.
We liked the location of the house. I should note that Titusville is not a major tourist town, so I didn't see a lot to do within a 5-10 minute drive. But, we really liked that the house is about 15 minutes from the great birdwatching and nature portions of Merritt Island in one direction (that's why we were there; the wildlife drive on Merritt is great), and about 15-20 minutes to Kennedy Space Center in the other. So, it takes a car but there are some good sights nearby. It's a little far as a home base to Universal or Disney, but that could be done. We drove directly from the house to the airport on our last day and it was an easy, maybe 45-minute drive.
Overall, we thought it was a great house at a reasonable price, a very responsive and friendly owner, and an excellent experience. I would highly recommend it.
