We stayed in this hotel one night as our flight to Keflavik arrived late at night. The hotel is nothing special, but has a very convenient location close to the airport and a decent cost-perfomance ratio for Iceland, especially if you get an early booker rate with 25% discount as we did. The breakfast was also very good and also good value for approximately 7 Euro per Person. We would definitely stay there again.

The room was quite trendy, spacious and comfy, considering it's an airport hotel.
The bathroom felt like one of those self clean toilets where the walls, etc can just be washed down, though.
Didn't have breakfast, so can't comment there.
There isn't much to do around the hotel and when we were there it was very windy, which was rather tiring.
There is, what looks like, a good viking musem in Keflakiv though. And a couple of old grass roofed houses can be visited, which is an option if the need to kill time is there. Bus 2 takes you there.
Blue Lagoon departures are from the hotel. We didn't do that because it seemed overpriced.

We stayed here first before going anywhere. After a very long flight we needed a good resting spot, and this was it. The breakfast isn't anything fancy, but the room was good and it is central. You can watch the teeny bopers drive their cars up and down the main street and yet it is still quiet enough to sleep soundly. Walking distance to all restaurants, and other attractions in Keflavic. The tap water is not drinking water. Driving distance to other attractions like the Blue Lagoon, Beaches, and other attractions in the area.

Stayed overnight in the hotel on my way to the UK for business. I loved the surrounding town and the hotel was very clean, very realxing and most of all very comfortable. Although my stay was short, we did have dinner there and although not many folks in the dining room, it was very enjoyable. Being as this was my first time ti Iceland, I had a bit of trouble getting to sleep due to the fact it was light most of the night. But I am sure if my stay were loger, I could have adjusted nicely. I got really good vibe being there and would recommend it to anyone!
