Overall a solid place to stay for our family. We are American, were traveling with a toddler, and are also (somewhat annoyingly) vegan. So with that in mind, here is my review-
Great location within close walking distance to Vondelpark and a ton of dining options, grocery store, playground, etc. We were able to walk to the Rijk museum, to every meal out, etc.
Very friendly staff, and our favorite part was that they had a 24-hour cafe right in the lobby. There is another Conscious Hotels location just like 3 doors down, with another 24-hour cafe in the lobby and a great restaurant. Both cafes had great vegan and vegetarian options, I'm talking like, 4 different vegan pastries and every type of plant-based milk you could dream of.
The only thing I didn't like, and this could just be a very American thing I think, is that the rooms don't have AC (or at least, not AC that is controllable by the guest), bathroom fans, or mini fridges. I knew this going in due to the property description, but underestimated how annoying it would be. The room got uncomfortably hot a couple days, and humid after we showered due to no fan, and we were just lucky it was cool outside so we could crack the windows for some relief. And the lack of fridge meant no leftovers or grocery/milk storage for our kid, so that was inconvenient, but not the end of the world since we were so close to stores and cafes anyway. Overall, 4/5 experience for us!
