The smallest room I've ever been in my life. I guess apartments have better comments, I did not get to see one. We stayed in a house with at least 8 bedrooms, all depending on 1 shared bathroom for men and one for women. If you only have 2, you should not label them "men" and "women", let people use any of them. This is an issue unless you are willing to wake up earlier when everyone is sleeping, that's what we did.
Breakfast was not included but we decided to pay for it. The staff is not paying much attention to restocking pastry, coffee and other items (variety is not much anyway). At first, I thought they did it on purpose, so you don't eat much, but even though new guests were coming they did not move fast enough to brew fresh coffee or bring more food. Breakfast was $31 per person, expensive as expected in Iceland, but quantity and quality are not worth it.
Guests love the geothermal area, but don't let this distract you from the other things you don't get. On a positive note, this could be your option to lower hotel costs at the end of the Ring Road adventure, that's the way we saw it!
