Me and my girlfriend spent a week in Hamburg for about that last year.
Admittedly, half of it was camping at a music festival.

I imagine the boyf would like that.
I would like clean sheets, nice walks, nice history and a bit of seaside.

Hamburg was like that apart from the seaside.
Stayed in a hotel for a few days, fucking good food and at the time it was pretty cheap.
edit: there are nice lakes to walk round and old buildings to look round if you fancy them.
And a bombed out church tower you can go to the top of and get nice views from.
