sleep and silence

a spot in someone's garden...?

Hello everyone,

I don't really know where to look so I thought "casa-ists" might be able to give me a bit of advice!

I am in the mood for planting a tent in a green area, where my needs would be : toilet, access to tap or fresh water, quiet sleep, organic grapes, privacy/solitude when I wish, and no scheduled activity (or little) (or I could do some work but not too tiring and not too many hours). :)
I have a bit of money, but not much.

another option would be of renting someone's van for a little, but I don't know if that's possible.
