Being at Ellen's place was the best decision we took in our trip to Amsterdam. The room was very clean, warm and quiet, the beds amazingly comfortable all of them, we sleep like angels.
It has good transport connections where you can finish the details of what you are going to do when leaving the bus or the ferry; with all the tips Ellen gave us it was very easy to move around.
We sincerely recommend Ellen's place to everyone. Definitively we'll come back.
Rosa, Ana, Lorena and Maya.
