The room was very nice and clean. I’m guessing air conditioning isn’t a big thing in Iceland as it didn’t seem our room had it. We could control heat only but didn’t need it. The included breakfast buffet was plentiful and had many options. We ate there every morning. The staff was very nice and friendly. Highly recommend.
