Hello friends ... an odd request ...

I will be arriving in Europe (specifically, Oslo, although I am not bound to this location, and in fact would prefer to transit elsewhere) at the end of this month for about 40 days. I am a writer and have been looking for a place to 'hole up' and get some significant work done (I am several err... months ... late on a deadline.)

- I'm looking for something relatively inexpensive (around $1500 USD)
- Require absolute privacy, quiet, and solitude -- I do not want to live in somebody's basement or in a setting where I will be bothered. I need to be alone with my own mind (does that sound crazy? )
- I do not mind roughing it; internet, running water, indoor toilet, electricity not essential
- Needs to be in some way accessible via public transit / walking
- Preferably within 5-10 miles of a grocery store
- Safe!

I have tried AirBNB, and there are some interesting options ... but nothing that entirely fits the bill.

Any suggestions? Thank you in advance for any advice you might have!
