Fantastic location in a central area of Amsterdam - walking distance to all of the major sights and attractions. Additionally, it is one block from the metro (which I never used, because I walked everywhere), :-) and two blocks from a grocery store. It's also located on a side street with virtually no noise at night. I'm a light sleeper, and even during the enormous LGBT pride festival, it was very quiet at night, which made me very happy.
Things to be know in advance: the flat is very small, even for a studio, and very modest. It is not a luxurious space by any means.
In my opinion this studio is best suited for solo travelers, coming to Amsterdam for only a a few days, who enjoy lots of walking, and don't require fancy touches to be happy.
