While Ijburg may look a bit far out on the map, it's only 15 minutes to Centraal station. This is a great area with grocery, restaurants, and cafes all within a 5-10 minute walk. The tram station is 5 minutes away with easy and regular connections to the core of Amsterdam.
As far as the apartment - spectacular. A beautiful place with a beautiful view. Lots of room for a family. We are 2 adults and 2 teens and there was enough room to spread out and recharge. Everything was perfect - kitchen and supplies, wifi, etc. It was like moving into a friend's apartment for a few days.
Note that it is 3 flights of stairs to the apartment. It wasn't an issue for us at all but should be noted if you have mobility issues.
The hosts were fantastic. Very responsive to all communications, and extremely kind. Little touches around the apartment made us feel welcome.
We would absolutely stay here again, and recommend the apartment without reservation.
