We've booked both floors from Lins apartment, the 3rd and the 4th. We stayed there with a group of friends and it was really awesome! A great spot, next to Leidsesquare where you can enjoy really nice bars. I would highly recommend this spot when you want to visit Amsterdam with a larger group. The apartment is spacious, and very clean! We met the cleaner when we arrived, together with the host. She was very friendly and made up exactly the beds that we wanted to. Overall experience: 10 out of 10! Very great.
