This young person's flat is in a convenient, quiet location, a half a block off one of the most beautiful canals in Amsterdam. Staying there gives you both a sense of living in a real Amsterdam neighborhood, yet also being close to some of the tourist attractions. The beds are comfortable, TV and WiFi work well, as do the dishwasher and washing machine. There are racks to dry clothes. There's a big table for working and eating, and the bathroom is modern.
The drawbacks were:
it's a fourth floor walk-up;
the kitchen barely has enough tableware (e.g., only four forks and no table knives), has no electric or stovetop kettle for hot water, and its cooking equipment is very limited - it's the kitchen of someone who rarely eats at home;
and there are no room fans for hot days - we had to leave the windows open to sleep and were eaten alive by mosquitos.
Twan, a manager for the owner, was courteous and always prompt to respond by email, although he could not remedy the deficiencies.
