+ Good value
+ Fairly central and well connected by tram
+ Reasonably clean
+ Free breakfast - continental and simple, but good croissants
+ Quiet stay
- Super small room
- Not much going on nearby
- Not for those with mobility issues (massive staircase at entrance)
- No ventilation in the room
Conclusion: The hotel is good value, but the hotel room is absolutely tiny (even in the context of typically small European hotels). Our room was so small you couldn't open the bathroom door the entire way without it banging into something. If you are ok with that, the location is decent and reasonably central.
Tips: The hotel looks close to the train station but it sort of isn't (solid 20 minutes walking). I recommend taking the taxi which costs only 7 euros (only slightly more than buying transit tickets). For directions on how to get from the airport to the train station, you can buy tickets at the machines by the entrance to the train platforms. Our credit card worked, but it didn't for everyone. Look up the schedule on the boards and you can take any train that passses through Amsterdam CS (does not need to terminate there). The ride from the airport to CS is around 20 minutes. You can also buy a Hollandpass at the Travelex store at the airport if you want one, which I think is a fantastic deal.
