The host was very kind and helped us find our room upon arrival. Cleaning service was very nice and asked everyday of we needed anything and always gave us new towels, more soap, etc. The room had heating, which was good since we were there in winter :)
It was a reasonable price in Reykjavik for a room. No breakfast, normal sized hotel room containing a queen sized bed, a small desk and chair, water boiler and tea bags + creamer, sugar, etc.
The house itself seemed quite large and looked a bit like a white fortress on the outside :) Our room was for two people and was reached from the side of the house.
The floors got dirty after a few days of staying there, with us moving in and out everyday xD
Otherwise it was a cozy stay!
P.S. It is normal that the warm water smells sulphuric in Iceland.
