Barbara´s house was a great experience for us. We visit Amsterdam during August, we were 4 adults and the house just had more than enough space for everyone. It has big kitchen and all you need, breakfast at the backyard was nice and the cats from the house were friendly with us!. We recommend Barbara house as it is really close to many museums and there is lots of nice restaurants around, neighborhood is good and you get a supermarket 1 street away . You can rent bikes as par of your Amsterdam experience and you will be in no time in the city center or anywhere else.
