My grandma is renting out an extra bedroom in her house with two single beds. Access to a bathroom with a shower and a washing machine, dryer in the garage and TV in the living room. Breakfast, coffee and tea included (self service).
The address in location is wrong. If you look for Efstahraun on (Hidden by Airbnb) maps you will find a street and appendices, Höskuldarvellir is in the appendices and that is the right address.
