Great great great hotel. A true gem with a wonderful location 2 blocks to the sun voyager on the water and 3 blocks to the cathedral, and right on the main shopping street, Laugavegur.
Good breakfast too and if you can get room facing the back courtyard, its very quiet!
Our 3rd floor unit was spacious and clean, and contained good storage. Bed, linens, and pillows were excellent.
Will definitely use Fron as a base for future Iceland trips.
