Everything about Karen's home was just as described and was simply perfect for two couples. We had more than enough room to stretch out. Karen made our check in and out extremely easy, the house was sparkling clean when we arrived and knowing that I was excited about seeing the tulip fields this year, she even had two vases of fresh tulips there upon our arrival.
Before arriving, we were a little concerned about not being in the middle of everything, but there are two tram stops just minutes from the house and you really have the best of both world. You can quickly be in the middle of everything, but you get to return to a quiet, charming neighborhood to relax when you're done doing all of the touristy things. This made it so much better than our hotel stay in Amsterdam last year.
I wouldn't hesitate to recommend Karen's place to my friends and hope her home is available the next time we're in Amsterdam.
