Ellen's a really lovely host. She is very helpful and kind. She gave me direction guides once I landed in Schiphol Airport. Do not bother which kind of transportation cards to buy. Ellen will provide you an OV chip card for extreme convenience. In addition to that, she also printed out a large map for commuting from her house to Central Station and hot spots. I enjoyed living in her house mostly because I have my own space. I accidentally pass the private review; however, I would like to say thank you to her for my great vacation in Netherlands.
