Our house is a located at the bottom of a quiet street in a residential area of Hafnarfjörður, known for both being the elf and viking town. The house is 160 m2, not counting the garage. It has a garage and a small, landscaped garden with a porch. The house has three bedrooms, an office and one bathroom, living room, dining room, foyer, laundry room and a kitchen. In the master bedroom there is a double bed, in one of the bedrooms there is an elevated bed and in another a single bed. If more bedding is needed we can provide a travel bed in the bedroom we use as office. A cot for a small child could also be arranged.
There is also wi-fi in the house, PlayStation3 and access to Netflix on the tv. We are a family that loves games so we have a large collection of board-games as well.
Several playgrounds for children are to be found within 2 minutes walk. Within walking distance are two heated swimming pools, one indoors and other outdoors, both equipped with saunas and outdoor hot-pots, a gorgeous golf course by the sea, two gyms and a harbor with a small cafe. A supermarket is located within 10 min walking distance and there's a kiosk two streets away. Also within walking distance (15 min) is a small lake, Astjorn, with a walking path around it. If you are interesting in going riding there is a company offering riding tours located in Hafnarfjordur: Ishestar.
Our car will be at your disposal but if you want to take the bus it's only 2 minutes away and it goes straight to downtown Reykjavik.
Our town, Hafnarfjordur, is Iceland's 3rd biggest town including the capital, and it is a thriving one, with nice restaurants, good shops, a small shopping centre, art museum where concerts are regularly held, and more. One of the restaurants is a viking themed one, Fjorukrain, linked to Hotel Viking, where there are regular viking themed events. Hafnarfjordur is quite beautiful, surrounded by lava-fields and boasts a thriving scenic harbor.
ATTENTION: We have two cats, Lukka and Felix. They're both very friendly. If you would like to travel around the country for more than 2 days without coming to the house we would be able to arrange for someone to feed the cats in the meantime. We also have 5 hens that provide eggs every day, they can be left alone for 2 days as well. The eggs need collecting and would of course be yours ;) Their water supply is two days for a time.
We have not done swaps on this site before but have done so once through another website. References can be arranged if wished for.
