We spent 2 nights at the doll house. It is a completely off-the-grid house, with electricity from the solar panels on the roof and rainwater for the shower and the tab. That being said, there is a water heater, so no worries about warm water after the sunset ☺️
Depending on the time of your stay (we went in February) it can get
cold there. So remember to bring some warm clothes with you.
The only thing you have to keep in mind is, that there is no WiFi and the mobile service for us (t-mobile) was very limited. After all, it is what it says: off-the-grid ☺️
