I cannot agree more.
I have tried to point out to other Trip Advisor users of my experience in this regard. However it does not seem to have been well recieved.
There is a problem, in the hotel that I stayed in most definately, viz the Kap Hotel.
The manager went on the review to say that I must have been to too many coffee shops. That is not the reality, the reality is that Amsterdam is becoming like a health hazard, but this seems to be of no concern to anyone.
