I am a 46 year young, grey-haired, guy living in Rotterdam with my wife and my two daughters (9 and 11).

我为什么加入 Couchsurfing

I love traveling and meeting people from other places, with other lives, insights and vantage points. Hosting people is a perfect way to get in touch with the world and it's citizens. It makes you see your own place with a visitor's eye and appreciate it again.

I used to be rather active as a guest and host on Hospitalityclub.org (find me there as preitsma) but moved to CS now.

We have a guest room for one or two night and can provide some tips about what to see/do in and around Rotterdam.
