This apartment is BEAUTIFUL! Ester made it so cute, that I couldn't stop taking photos of interior and sharing with my friends ))) Communication was so welcoming and kind, that I can say it is really one of the best experiences in Amsterdam.
Just beware of 40 steps of the staircase from the street to the apartment level - this will may not suite to heavy big people or elder ones. If this not an issue for you - book this apartment asap!!!
Close to RAI (you can take 20 min walk), close to the center. One of the best locations I've stayed in Amsterdam.
