I would highly recommend Margot's place for a stay in Amsterdam - the apartment is clean and has everything you would need. Margot was great to work with and very responsive, and even provided a bottle of wine, cookies, and breakfast foods. The location is good, it's on a very quiet street right outside of City Center. The only comment I have is that when you arrive you may want to avoid walking from Centraal Station to the apartment as the walk is through the busiest part of the city and is a little chaotic if you aren't sure where you're going. Otherwise we were extremely happy with our stay!
