rooms are way to small, I had the impression they put 2 persons in 1-person room, could not walk around both at the same time.
There were hundreds of dead flies in the windowsill
Service in restaurant sucks, starter was served at the same time as the main dish.
Espressomachine was out of order, IrishCoffee was on the menue but waitress had never heard of it.
No excuses, nothing.
Manager offered us a free beer after dinner which we refused since
we had wine during dinner and did not ask for anything free.
We just wanted value for our money.

Don't book this hotel, there is a 3-star hotel hotel across the road,
named Hotel Myvatn
