The good contact between the owner family of the guesthouse and their guests, the help, the nearness to the town and the quiet of the place.
The room door couldn´t be closed from outside (leaving the room. There was no washing-basin in the room.
Very friendly owner - Arny, who had stories to tell about the volcanic eruption in 1973, which is the most important thing that's ever happened there! Well-positioned guesthouse, with basic cooking facilities. If you go there, take Euros cash, as they keep their value better than the Icelandic Kroner.
Bunk-beds to sleep in, so not the most romantic!
Easy access, good local walking and nostalgia in seeing places I had not seen for 44 years.
