The apartment is clean, well located and well equipped. You can prepare breakfast or dinner there. Neighborhood is quiet and there are some nice restaurants next to the apartment. City center is very close. Well connected to airport.
There are two issues which must be considered.
1. Stairs to apartment are very steep. It is historical tradition of building houses in Netherlands, so Foppe can't do anything with that. It can cause problems for those who take big and heavy bags with them.
2. Beds are like camp beds. Good ones, but still. For us the beds were OK, but if there are bigger people, it can cause some inconvenience.
Foppe is very nice host. I really recommend staying at his apartment.
