We spent a week in one of the apartments of Manuel Antonio Estates, and it was outstanding. The setting is gorgeous; feels like you're in the rain forest. Other than a few dogs barking, the location was very quiet, and felt secluded even though it was very close to town. We even saw a family of holler monkeys by the pool! Speaking of the pool, it was very well-maintained, and pretty private.
We made the hike to the waterfall on site. Be warned, it truly is a hike. From the apartments, we had to climb several steep hills before even getting to the trail. Once we got to the trail, it was a narrow and steep hike down to the waterfall. This is not for the faint of heart, but well worth it if you go. The waterfall was absolutely beautiful and serene. It's deep enough to swim in, but there are also several places to just relax in the water. You could even have a picnic on the rocks there. Unfortunately, some people did leave behind some trash, but it didn't take away from the beauty of the place.
Raindrop Spa is also a must visit. Very professional services, with an incredible view. The couples massage was the most relaxing thing I've ever experienced.
The property is very close to town, so you could easily walk into downtown Quepos for dining or shopping. The marina is about a 15-20 minute walk away, and you'll find better shops and fancier restaurants there. Easy access to Manuel Antonio for all of your excursions as well.
Dorit and the rest of the staff were great to work with. Communication was great, and we had no problem with check-in or setting up excursions. Everyone was very friendly and welcoming.
If I were to pick one nit, I would suggest better cleaning services. The apartment looked clean on first glance, but upon further inspection it could definitely use a deep clean. There were several cobwebs and dust throughout the apartment.
Overall though, this place is great; especially for the price. I'd definitely stay here again.
