The apartment was clean and a really nice place to hang out. The wifi was fast. The shower was built for tall people (I'm 6' / 182 cm and it was well above my head.) It was a 20-minute walk straight down Laugavegur to get to most of the things we wanted to do. A nearby 10-11 convenience store was helpful.
When we arrived at the apartment, the key box was jammed and we couldn't get our key out to let us into the apartment. I called the owner and he answered immediately. He explained that he was out of town, but that he would find someone to help us get in. Within 10 minutes, a friend of his drove up with a set of keys to get us in the apartment. I was very satisfied with how everything worked out, and with service like that I can recommend this place to anyone knowing the owner will take care of problems.
