Jan is a easygoing, flexibel and relaxed host.
My sister and I had a nice time in Amsterdam staying with him. There was no problem at all changing the checking-in time at the day off arriving. We had nice conversations and exchanging tips.
The construction of the house makes that you have your own privacy, for guests and host, there is also room to spent time together.
Next time when I want to visit Amsterdam I definitely will try to stay at Jan's apartment again.
Thanks, Jan , see you next time!
