Hans' apartment is in a stellar location--right over the Albert Cuyp Market in the De Pijp neighborhood. This gives easy access to museums and the canal district (10-15 minute walk), but is far less touristy than being in the city center. There are many great places to explore and eat at nearby. We were a little worried about the noise from the market, but it was not too big a deal, especially if you stay in the back bedroom. The front side can get a bit noisy around 6-7:30AM.
Communication with Hans was easy, and his neighbor let us into the apartment and gave us all the help we could need. A great place to stay in Amsterdam! We only wish the weather had been better so we could enjoy the rooftop deck!
