My wife and I wanted to bring our kinds down to St Augustine for a couple of days at the beach. The place was lovely, and in such a good location. Super easy to walk to the beach (we have a 2 and 3 year old), and even easier to walk to neighborhood restaurants. Other than the grocery store, we never had to use our car.
The duplex is small, but works great for a few days, or if you have a smaller group. There was no washer and dryer which was okay, but would have been an issue if we were there longer than a couple days.
Only real issue we had was the A/C unit stopped working on our last day. Was able to get in contact with the owner quickly to trouble shoot a few things. Ended up having to wait until the next day for the repair guy to come and fix it. It was a very hot night sleeping, but were refunded for that last night of the stay.
Overall, it is a great house for 2-4 people looking for an awesome beach town in a very convenient location to everything.
