The flat is really nice and in particular it has a great view on one of the most beautiful canal of Amsterdam.
The neighborhood is very central and packed with nice shops, restaurants and bar. Everything is at a walking distance.
On top of that the flat as a lovely terrasse that we didn't have the chance to use because it was November, but it must be great during the summer. Ellen was very nice and very helpful (she even packed the fridge with food and water for the babies, and wine for us, in the fridge). Great place and great host!
