I had a really lovely stay at Christel's place. The apartment is really spacious, with an incredible living area, and beautifully done up. The street is quiet and pretty, and there's a Carrefour supermarket just around the corner. Easy walking from Centraal station, and you're less than fifteen minutes walk away from the University and some of the bigger, busier 'touristy' streets and squares as well, but have your own quiet space to come back to when you're ready. Highly recommended!
