We really enjoyed this hotel for a nice, clean, straightforward overnight in Reykjavik. It's not a high class luxury establishment but a very well executed 3-star hotel with a great cozy feel and excellent service.
The staff were uniformly excellent, from check in to check out to restaurant/bar staff. We had a sea view room which was nice, but unfortunately the view is over a parking lot and a main road, and is therefore a little less exciting from lower floors (we were on 2). The rooftop bar has stunning views of the summer sunset and has a cozy, fun vibe. The breakfast buffet was served in the same sky lounge space and was small-ish but well done, with a variety of cold and hot options. The hotel has a cozy front lobby and well-thought-out storage lockers for those who need a space to store luggage before check-in or after check-out. We didn't try the spa. The rooms are perfectly clean but pretty spartan/efficient: small square footage, not much of a desk to work at. Our room had a single bed in place of a sofa, so there wasn't really even any seating. The bathroom is small and uses a wet-room shower approach. All perfectly workable, but just a little tight, even for two people. The location is very good, on the water, and a two-block walk to the main town road and just a few more blocks to the main church. It was a (cold)12-15 minute walk to the harbor for any whale cruises. Overall, we would definitely stay again as a value option with a great feel.
