We really enjoyed our stay and home base of Hellnar. The cottage was as described. Very comfortable and accommodating for our family of four. The mattresses are excellent. The kitchen is well equipped and stocked with basics like olive oil, salt, pepper some spices, coffee, sugar etc. This makes cooking so much easier! The only caution I would give is that the stairs to the second floor a cross between a ladder and stairs. Not a problem for us but if you have mobility issues or toddlers, it might be hard to get to the second level where the bedrooms are.
There are a lot of things to do near Hellnar, so it is a good base to see the peninsula. There is also a very helpful information office just next door. You can learn quite a bit about the area there as well as get maps for hikes.
