We really enjoyed staying at Walther's apartment in De Pijp. The apartment is very clean (not even dust!) and Walther has a very well kitted out kitchen - great if you are going to do self catering - even sharp knives. The main bedroom has a huge, comfortable bed. The second bedroom is pretty small but fine for our two kids for sleeping. The apartment has very steep steps from the street to the door - but after spending a few days in Amsterdam we noticed this is common. Walther really encouraged us to relax at his house - he was welcoming and generous. You can walk to the Rijksmuseum, Van Gogh Museum and public transport to anywhere is at the end of the street. A cool part of town with nice bars and restaurants.
