We stayed here after hiking from the north side of Isla del Sol. The email communication was prompt-although I don't think advanced booking is necessary here or anywhere on the south side. The room key situation was interesting with just a pad lock securing our room. The place seemed like it was in repair and our room could have used a coat of paint and some new floors. The cleanliness was decent although not overly clean, a few dead flies here and there. There was no mirror in the bathroom but that wasn't a big deal. Breakfast was average. On the plus side, our hostess was very friendly and the views were outstanding! Make sure you have US cash because that's all she accepts.
