OT: Anyone somewhere in Europe to host me?

I’m planning a trip to Europe starting on mid-September.
I will go as a backpacker and on a very tight budget. Hence, I’m looking for people to host me at different locations, and where I’ll be able to stay for at least 3-4 days (and maybe up to a week or so) to get to know each city in depth.

I know there are websites for this (like CouchSurfing), and I’m also searching there, but I’d rather stay with someone like-minded that shares interests with me, because that way it would be more fun and enjoyable.

I’m a very honest, responsible and considerate person. If anyone was willing to host me at any place in Europe (big cities preferred, because it’s easier and cheaper to get to those), I’ll be very very grateful.

You can contact me by PM.

Thanks in advance,
Martin
