Q-Park Museumplein is in a very good location, designed to serve nearby museums including the Van Gogh Museum, Rijksmuseum and Stedelijk in Amsterdam, but comes at a huge premium.
Parking rates are between € 1.60 - € 2.75 for every 15 minutes, so can generally cost between € 6.4 and € 11 per hour, which seemed crazy for me, even for such a good location, as the car park wasn't too clean and was unstaffed.
The one positive about charging for 15 minutes at a time, rather than hourly, is you could end up paying less, if you just go over the time by a couple of minutes, but the rates are so expensive anyway, it feels like you won't be saving much at all.
They have public toilets here, but they come at an additional cost whether you are using the car park or not. I can totally understand them wanting to make some money out of tourists not using the car park, and keeping them out of the toilets, but if you're using the car park, you're basically paying twice.
I did use the toilets and was unimpressed at having to pay € 1 to enter a dirty toilet, which was cash-only, to make matters worse they only had freezing cold running water, it felt like washing my hands with a bunch of ice cubes!
2* - Straight-forward and easy-to-follow car-park in a good location, but high prices, poor cleanliness and lack of staff pretty much make it an advertisement to use public transit. read more
