The location is unbeatable. You are close to the city center but not on it which is nice specially if you come in the weekends. Walking to it takes like 20 minutes and by public transport it takes like 10. Highly recomend on purchasing a ticket since it comes in several formats (1 hour, 24 hours, 72 hours and so on) if you are here in winter or planning on going to use it a lot. Hans gives free bikes to use and they are not new of course but they get the job done and you can use them whenever you want. If you go on summer or spring this is perfect to know the city as a true Douch. The bike tour he does is for free and you get to know a bit of how the Netherlands gets to stay above the sea, takes like 70 minutes and is to a part of the city you wouldn't honestly see otherwise. The Adam's lookout discount he offers is of 50% and I would take it whit my eyes closed since the lookout is a must go! The boat trip is nice and he sells them cheaper that the actual tour guides, I know because I pay full price, don't be like me.
Totally recommended.
