Stayed as a group of 4 here. We were rather hesitant at first due to the glass floors, but this place was incredible and we soon got used to them. It is even more incredible than in the pictures. The place itself if a work of art. 10-15 minute walk to the train station where you can easily get anywhere. Benno was very friendly and easy to contact. We were able to get great suggestions of places to eat and visit. Definitely recommend it, and if we are ever back in Amsterdam then we would most definitely stay here again!
