What a pretty sight! The hotel rests at the edge of a collapsed volcano that became the second largest lake in Guatemala. You will probably like the outdoor dining area that overlooks the beautiful lake. You will especially like the gorgeous, well maintained grounds with their lush gardens. The room isn't anything to brag about, but they have plenty of American TV to help you keep up with your regular programming. The plumbing seemed to work well, which I have to say is a great thing in this country.
The market at Santiago Atitlan was fun to visit, but take a partner with you, since they gather around you like flies and don't want to leave you alone until you've heard their various offers. It would be good to shop there before you buy anything from the hotel's gift shop, since their stuff is high priced. If you need Pepto Bismol, they have that there.
The Internet works fine in the bar and restaurant area. The weakest area is the lobby.
Overall, the hotel is quite nice and a good place to stay for a couple of nights.
