The Hotel Wiechmann is rated as a 2 star hotel, but it is a very good 2 star. However, I found the price I paid reflect more like a 4 star hotel than a 3 star.
It is a very clean hotel in a good location. The staff are very friendly and helpful. The stairs are very steep, but this is an old building and to be expected. Especially in Amsterdam. I can't comment on breakfast as we were always too late for it. That's our own fault.
Overall, the stay was pleasant, but expensive.
