Joop's place is in the best possible location you could imagine. In a super hip area of the city with tons of shops, restaurants, and bars. It's really an amazing spot on the canal, and was our favorite part of the city, so from a location perspective, it cannot be beat.
The spot is about a 5-8 minute walk to a tram stop depending on where you want to go, and the museums are about 15-20 minutes walking, which was fantastic.
The flat itself was nicely equipped as is described in the listing. We were quite comfortable and had what we needed to make simple breakfasts and relax in the evening.
The only downside to this flat is that is it a bit noisy - if the neighbors are making noise you'll likely be able to hear it. But it's not enough to deter us from staying here again. We would stay here again for the location alone when we return to Amsterdam.
