We’ve been to LBTS a few times, but this was our first stay at Roberto’s. We loved being RIGHT ON THE BEACH. I got up a few mornings to watch the sunrise and just had to open my door! We were a 5 or so minute walk to the restaurants/stores/plaza/etc. We didn't have a car and that worked fine for us.
The property is super clean and well managed. I think there are around a dozen units. There's a pool, some hammocks, a few bikes, beach chairs and umbrellas, and beach towels.
I agree with the other reviews that mention the thin walls. I think I was kind of self-conscious because I could hear some of our neighbors' regular conversations - no one was being loud or disrespectful.
We would stay here again in a heartbeat! I wouldn't have thought of it myself, so I'll point out that there's a potential downside to being right on the beach. It was a little cool and very windy during our stay. The weather wasn't ideal "beach weather", but since we were right on the beach, it was hard to escape. Even a block or 2 further in would make a difference on a windy day.
We had a wonderful vacation and I'd recommend Roberto's place to anyone!
