We visited this place in September. Rented little house for 7 people. House was clean with all necessary facilities. Excellent place for internet detox. Please expect that there is no electricity and phone reception. But that is the beauty of it. At the evening before the sunset you can cook dinner together and then at the large table have interesting live stories. And because there is no reception and internet every one is engaged 100% engaged and not disturbed.
Please note it's not a luxury 5 star accommodation. It's fun accommodations.
When we visited the camping had hundreds of tents and campers. The shared facilities are not able to accommodate everyone and looked terrible although the effort of the staff. The only reason to visit is the geothermal river, but because of the many people it's not really a pleasant experience.
