Hands down, the absolutely breathtaking views you get from this house make it well worth the price tag. Additionally, the inside of the house is very well designed with many unique features, such as huge, sliding windows and doors, rock walls, and a giant soaking tub/shower combo. There is a fully stocked kitchen so that you can cook all your own meals, and the view you'll have while cooking is spectacular. There is a great little futon outside on the porch where, if you're like me, you'll spend every spare moment gazing out at the lake and volcanoes, as well as a hammock where you can watch a different sunrise and sunset each morning and evening.
The drawback, however, is the noise. The rental is located on the bottom floor, and the upstairs is lived in. There is a child on site that can be heard running, jumping, banging, bouncing balls, etc. just overhead, and it is not just a muted, muffled sound. He also yells quite loudly when outside. For us, this was not so terrible as we spent the majority of our time out and about hiking and exploring the cities around the lake. However, there were a few afternoons that we wanted to relax after a very active day but could not with all of the noise. I wouldn't say that I would have booked somewhere different knowing what I know now, but for those people who want a peaceful retreat, just know that this might not be for you.
The only other drawback is getting here. Many of the public boats on the lake do not understand when you ask for "Tsan Cruz, la casa privada", which can be very frustrating. We had one boat try to charge us extra to drop us off at the private dock.
Overall, this is a beautiful rental inside and out with jaw-dropping views for a once-in-a-lifetime stay on Lake Atitlan.
