Our stay at Koen's and Regine's lovely apartment was absolutely wonderful. The flat is gorgeous, neat, and clean, the balcony is fantastic for having breakfast, lunch, dinner, drinks - one of the most beautiful places ever! The location of the apartment is great as well, there is a supermarket in the same block, the bike rental about 5' away and the city center really close by. We did everything by bike or foot and we got to see a lot of the city, although the place was so nice we wanted to stay there a lot as well. The five steep floors are not for the faint-hearted, but the flat is so cute, it would be worth double the workout as well. We'll gladly come again, if we can, any time we are in Amsterdam!
