I have been to Amsterdam many times (7 to be exact) and have never stayed at such a well kept bnb. Matthijs is very kind and thoughtful. He made sure that we had a few cool places to see and communication was incredible. He responded so quickly and took care of everything! we loved staying in the area. It is very central and easy to get to from Central Station.
He also included Breakfast. You get a voucher to use at a place called The last crumb, don't miss it....it is amazing! It's a very nice walk along the canal to get to it.
You won't find a better Host or place to stay in all of Amsterdam.
