We travelled (2 x adult & 5 yr old) and stayed in this hotel. While not cheap, the accommodation was fantastic. We shared a room with our son, he slept in the fold out couch which turned into a queen bed. The whole room was clean and comfortable. While not large there was enough room for us all. From check in to check out - the experience was hassle free - the staff was very friendly & accommodating. The breakfast amazing too.
Located in the heart of Amsterdam so easily accessible to all the major sights.
