I enjoyed with my girlfriend of a weekend.
The location is perfect, you´ll feel relaxed on a quiet location near the main villages and towns on the north.
The place was spottles, very tidy.
The owner was very easy to reach and helpful in the location of the place (which is very easy because there is a sign in the road)
The house is huge, brand new and very well equiped (kitchen with all you need, two toilets with showers, hothub in the outisde, ready to use)
Warm, surprisingly affordable to the Icelandic average prices for lodging (and I live here). Near the lake, with basically no luminic contamination you have a very good chance of spot beautiful northern lights.
I see myself renting it again.
