I booked Nathalie's apartment for 3 nights and I couldn't have made a better choice. You can reach it easily with the public transport or even by foot since it's located so close to the city center (30-40 min).
The apartment looks exactly as shown in the pictures. You'll have the chance to experience the best sleep in your life and the futuristic-ish shower head and knobs (you need to solve a puzzle in order to turn on the shower). Nice TV, though. :)
If I will ever comeback to Amsterdam, this is a place where I would like to stay.
