Small guest room in my apartment with queen size bed in small city outside Reykjavik. Travel time to KEF airport is 30 min in a car so this is a good option to have a night before early flight or night after late arrival. As this is live in place, i will be selective of who I accept as a guest.
There is a 15-20 min walk to the Hafnarfjordur City Center where you can take bus to airport or Reykjavik.
NOTE: There are cat and dog here so you have to love animals to survive.
