My fiance and I recently had the opportunity to stay at Casa Gaia. Even though we were technically in the off season, it was truly a magical place. We arrived quite late in the evening (10:30pm) and were greeted by Walter and Graciella (the property managers). With a smile on their face they happily got fires going for us, put away groceries and generally made us feel very welcome.
The property itself is very private but only a 10 minute drive (if that) to the town of Jose Ignacio. Between the view of the water, the arabian horses, the beautiful architecture (the pictures don't do it justice), daily assistance from Walter and Graciella, we'd give this property more than 5 stars if we could.
Casa Gaia is great for both families or for a romantic vacation. If you're planning on going to this area of Uruguay, do yourself a favor and keep on driving past Punta Del Este (30 minutes) to Jose Ignacio. You wont regret it
