The Sarphatipark flat is beautifully appointed and brilliantly located. It is a delightful place to stay in Amsterdam, with easy access to so many different places. Walking distance to everything contained in the Museumplein, Anne Frank's House, and with the tram only a few minute's walk away you have access to an even greater area.
The kitchen facilities are great and a good number of pots/pans/etc accompanying the stovetop and convection oven to make home cooking easy. Though, with several great restaurants right at your fingertips it's also easy to simply eat out (particularly the Lebanese restaurant 'Artist' on the corner near the apartment, and the cafe 'Scandinavian Embassy' for breakfast - amazing cinnamon buns).
Mike and Sabine both took amazing care of us while we stayed in the flat and went above and beyond to make us feel welcome. Overall, this place is a wonderful option for somewhere delightfully comfortable and convenient for a stay in Amsterdam.
