Overall : Decent place in superb location. Easy to enter with the code. Only issues were cleanliness in the toilet and pillow cases had an odour.
Pros : Location (walking distance to pretty much everything in Amsterdam). Decor (the place looks pretty cool). Coffee machine (good to have, but bring your own pods. Although, the cafe shop opposite is top notch as well).
Negs : We had to clean the toilet a bit ourselves (wasn't flushed, fluff on seat). Pillow cases smelt like they hadn't been washed with adequate enough washing powder. Only found two towels in the room despite seeing several in the pics. Had to go downstairs to fetch two more towels ourselves. A bit pricey I think for sure, but if small tweaks can be made ... great spot for solo travellers or couples.
