Maybe your dreams are more of sunny tropical islands, but I loved these remote cabins from a huge collection of photographs at http://cabinporn.com/
Which would you choose?
I can imagine myself staying for a month of writing in that first one, and I was lucky enough to spend Midsummer in a smaller version of the one above in Dalarna, the traditional heart of Sweden in a meadow just like this. It was magical. And romantic..
Thanks Julia for the link - you do find some lovely things!
