Looking to rent a furnished village house

Hello
Incidentally, I have stumbled on your website while browsing for accommodation in Bulgaria and I jumped on the opportunity to contact you for some advice you may provide.
We are an Israeli retired couple living in a city apartment in Israel. I myself have been born in Bulgaria and speak the local language.
I have some kind of a dream to live in a Bulgarian village not far away from a large city, so we can enjoy both,
My idea is to rent a hose for few months in a year for the beginning and decide latter if to buy.
Could you give me an idea for a monthly living costs should I have to expect before taking any measures and the possibilities to rent a small reasonable house in a fair price.

I apologize in advance for " jumping" suddenly into your life with no permission and hope you may help with advice we can fulfill our dream.

Thank you in advance
Sincerely – Joseph Sadeh
