Rob was very friendly.
As I was at the RAI and wasn't able to checkin in the evening, we arranged an alternative. Very uncomplicated.
The room was clean and silent.
Another sleepover in the room nearby was there, but bathroom was clean. so nothing to complain here.
A little breakfast with egg, bread, orange juice and coffe and a nice chat with Rob was very good.
WLAN was a bit slow, so don't expect legless streaming ;)
If you don't mind a little walk, you are at Station Bijlmer Arena in 15 Minutes slow walk or try to get the bus. But at weekend, you may need to wait half an hour, so walking ist faster.
In general, it is a very good location for sleepovers in Amsterdam :)
