Everyone is welcomed, the "Go see the world, you Americans!" was supposed to be funny and should not implicate that I 'prefer' to have an American as a guest.

You are welcomed if you are open-minded and non-racist (no matter what sex, skin-color).

If you are in a wheelchair or have trouble walking stairs, my apartment won't work for you (it's on the second floor) - but I can offer you to be your guide for the city and I can try to find a friends apartment where we can help you with an elevator.

Sorry for any misunderstanding/anger the last sentence provoked - seems like I didn't think that through.
