We flew in with 4 kids under 7 on a red-eye flight from New York and arrived at 8am in the morning. I was so grateful that he let us check in about 1-2 hours before the actual check-in time,
The location was very easy to find and access with google map, being right across the street from main station. The apartment is very spacious and bright, with a small selection of toys for our kids. Being right above McDonald's was a real life-saver when you're jetlagged and everything around you is closed.
For those with strollers, ours (a city mini) fit into the elevator so we had to fold it in half. There is also another flight of stairs to climb once the elevator takes you to the highest floor.
The apartment might also be more comfortable with some air-conditioners for the summer, because it gets really hot in the daytime.
