The location is unbeatable. No need for Google Maps for this one. Just go out of Sloterdijk Station, turn your head to the right, and there it is.
Sadly, everything else after that is beatable.
Reception: Cold, unwelcome experience at check in. Requested to write date of birth on form which is normal. The problem is being requested to write your age also, which should be easy from just reading the date of birth. Upsetting. Reception said to take key with you at night, as the main doors would be locked, which was soon afterwards. I went out later and arrived back after midnight, to find a crowd of guests outside, and the doors wide open for guests to come and go as they wish.
Room: Small, uncomfortable Single Room on middle of top floor, €110+ per night. Looked and felt like just another dorm instead. Good to have tv available, not good to have tv position at dangerous angle where guests could easily hit their head by accident, and have head injury. Small bed with pointless metal bar on wall beside pillow, where there could be a similiar incident as with tv. Soap dispenser in toilet was empty. View from window would be of biggest interest to window manufacturers, because it has amazing view of office blocks nearby, but not much else.
Accessibility: 1 elevator working at the time, for hundreds of guests to use, of the 3 elevators there. Long and frustrating delays during busy periods, as consequence. Understandably, some guests give up waiting for it. Using stairs would be faster.
Cleaning: Advised that the cleaning team do not clean the room every day. No issue with that. However, I spent second day mostly in room because of mobility issue, but allowed time to clean the room when they were near it. Room was not cleaned when I returned. 3 hours later, well into the evening, staff were still cleaning other rooms on the same floor.
Safety/Security: No locker or safe area, to store luggage or valuables in room. You just leave them in the room and hope that nothing happens. Other guests standing in groups in corridors, allowed to make as much noise as they wanted during night hours, and they did. Obviously, no facility available for wake up calls by reception, no real interest in providing one either, so if you need to leave very early and your phone has problem, you have a drama to deal with. It didn't happen to me, but that does not mean it will never happen to somebody else.
Again, all this experience was for a €110+ room per night. Amsterdam is expensive of course, but if you're offered airport hotel as an alternative, as I was, you should consider it. The Dutch train service is so good, that there will be no problem accessing the airport or the city, and you will get a peaceful sleep in a comfortable room, for considerably less cost than what I was asked to stay at this accommodation.
