Steinhusid is a really lovely little guesthouse, with a very well-equipped kitchen, and a big living dining/space with great views over the harbour, all on the ground floor. It has some incredibly cool, kitsch furniture in there, which makes it a really memorable place to stay. It's very peaceful - there's no wifi - so you can really relax.
We stayed in the largest bedroom, at the front of the house, which was very comfortable, although there were no cupboards or drawers to put things in if you like to unpack a bit. There was only one other guest staying while we were there so we didn't have any problems with the bathrooms, but there are only two toilets and one shower in the place which I can imagine might be a bit problematic if it's full of people.
The owner was very friendly when we went to collect the keys, although we had to go for a short walk (5 mins) to do this and meet her at her other hotel.
