My wife and I recently stayed with Karel while on our honeymoon in Europe. What more can I say then, if you go to Amsterdam then you have to stay with Karel. Not only is his B&B beautiful inside and out, but Karel himself is a wonderful person. Great location and close to everything, as well as large rooms with comfortable beds. I could go on and on, but after three weeks in Europe and 10 hotels, The Collector ranks at the top of our list. We will be back to Amsterdam for sure, which includes staying with Karel. Thank you for everything Karel!!
