My friends and myself stayed at Xander's place during one of the weekends in Amsterdam.
It is a great modern apartment located in an easily reachable area with public transport, restaurants, and shops just outside the door.
There was a little bit of an inconvenience during the check in, which was resolved very quickly.
Overall it was a great experience, however, I must confess that we were not able to find any hand soap, hence bought our own and the living room floor was a little bit dusty in some places.
That being said, I would definitely stay at Xander's apartment again and I would like to thank him for being our host.
