I stayed here for a long four day weekend with my wife and sister and we could not be any happier with the place. The apartment is close to downtown, yet also close to the main road leading out of Reykjavik, which makes it easy to get in and out of the city quick.
Pall and Dagrun were super friendly and helpful in answering any questions we might have about the area. We also rented their Ford Explorer SUV, which was very convenient and available to us at a very competitive price.
As for the apartment, it is very well kept and has a modern feel to it. The fully equipped kitchen is very nice to have as well. The shower was nice, and as it is Iceland, you can shower as long as you want without wasting energy.
If I travel to Iceland again, I will hopefully be able to book this apartment again.
