We took the whole house for a large group which was great as all of the rooms are a decent size. The kitchen area is good for a group - not that we used the cooking facilities! The house was clean and tidy - the accommodation is fairly basic but it was always warm and the beds were comfortable. There are only two showers which created a bit of a backlog in the mornings, but pressure/temperature was good (albeit water a little...eggy...suspect this is more of an Iceland thing!).
House is pretty central and easy to find - 5-10 minute walk to most of bars/restaurants. The bedroom downstairs is next to the kitchen and street so not ideal for a lie in!
Overall solid and reliable basic accommodation in a good location. The owners were very responsive to emails and very accommodating on arrival/departure time.
