Unwanted guest in our house (Netherlands)

Hello all,

This little insect frequently returns to our bedrooms and turns out to love humans (bites too!).
We went through quite a few books but came up empty.

Does anybody know what this is? It has a very tough harness too and is very hard to kill.

I could not add a picture through a website link so I have posted it on our website in our blog:

Thanks, Kees
