My husband and I stayed at Casa Yaguarete during our 3-week honeymoon in Argentina. We had a brief day and night in Iguazu to check out the spectacular Iguazu Falls. I'm so glad we stayed at Casa Yaguarete. As the website makes absolutely clear, la Casa is outside of town, which was our preference (we wanted peace and quiet, having flown in from BA). The guest houses sit on a lovely piece of land with flowering trees and birds. Our guest house was very clean, comfortable, and decorated quite nicely; we did not have any problems with the shower or plumbing. There are a couple of wonderful doggies who call Casa Yaguarete home too. We are dog lovers so this made us very happy.
But what makes this place utterly unique and a special place to stay is the fantastic owners, Lorena and Andrea. These lovely women make you feel like you are staying with old friends. We loved talking with them, getting to know them, and hearing a local, personal perspective on Iguazu and Argentina as a whole. Andrea cooked us a delicious homemade dinner after we got back from the Falls, which made us feel so at home. Lorena helped us arrange transportation for our entire stay (with a wonderful man named Guillermo, who was charming, funny, helpful, and great to meet) and was so friendly and engaging that we felt like we'd known her forever. We had a yummy and plentiful breakfast in the morning on the patio in the garden. The ladies took time before we left to give us suggestions on what to check out upon our brief return to Buenos Aires later in the trip; it was so helpful to get the inside scoop on what to see with limited time. Lorena and Andrea are simply awesome people and I'm so glad we got to meet them and enjoy their hospitality.
Re Iguazu Falls itself - the park is very well run and the Falls are a once-in-a-lifetime sight to see. There are a TON of tourists at the park, so be prepared and be patient. If you're looking for a hike off the beaten path, follow the green trail for about 4km (one way) to a gorgeous secluded waterfall - it's the perfect spot for a dip. Be aware that the park closes that particular trail at 3pm (the park itself closes at 6pm) so make sure you're on the trail in time. There is a good but overpriced restaurant on the park premises if you're looking for lunch.
Andrea and Lorena, if you're ever in NYC, shoot us an email. We'd love to see you again, and thanks again for your wonderful hospitality. You made our visit really special.
