The apartment was very spacious, clean and well decorated; it's so lovely! It has everything you need to have a confortable stay (sheets, cook utensils, towels..). The neighborhood is very quiet, altough it's not near to the center there's a bus station nearby and you can also go by bike (if you want to feel like you're living there, try the bike!), and there's a supermarket, some restaurants and also cafeterias nearby.
About Julie, she was the nicest host we could find! She was very helpful, she was always available and she answered every single question that we had (how to get to the apartment, how to move around the city...). She also lend us bikes, and she bought us some food and drinks to welcome us!
If you're planning to go to Amsterdam we really recomend you to stay in Julie's apartment, not only for the lovely and confortable place, but for the help and attention that you'll recieve from Julie!
