"overall excellent experience "

"very clean and spacious room"

"I doubt you can find a better view of the Arenal Volcano than at Arenal Observatory Lodge, plus the property is gorgeous and filled with wildlife (so many birds and a troop of monkeys swung by one evening). This isn't a fancy place — more old school — but if you're looking for a peaceful space to reset and experience nature, it's perfect. We'd stay here again."

"This hotel is amazing, the rooms are very large, clean, and close to everything. The staff is incredible, helpful, friendly, they go above and beyond to help. I would highly recommend this hotel "

"Great breakfast and clean rooms"

"The Springs is truly heaven on earth. I've been to Costa Rica fiver times since 2015 and my stays at the Springs have been most memorable than all of my other trips combined. Yes, it is one of the most expensive resorts in the area and I'm frugal but every dollar spent at the Springs is absolutely worth it. From the moment you arrive, everything feels intentional, thoughtfully, and beautifully maintained. Dining, the hot springs, Club Rios, the rooms, dining - every part of the experience has been incredible. It's been a month since my family's last stay and now that I'm back in the States, I find myself thinking about the resort almost every day. One of my favorite memories is sitting alone in a hot springs at 7am, watching an iguana float across the pool while rain fell around us. Moments like that is priceless. I would absolutely return again and I'm incredibly grateful for Mr. Lee Banks who created this amazing place. "

"The hotel is spectacular; the thermal waters flow through pools seamlessly integrated with nature. The service from reception, housekeeping, and the restaurant is outstanding. There are also excellent excursion options."
