The location is just perfect to explore Amsterdam: one way to the Museums, another to the centre. Right in the middle of the canals. Can't get better than that. We loved Leidseplein just outside our front door - spent hours there just soaking in all the different cultures living in and visiting Amsterdam.
A few steep steps, but that is to be expected. While in a very busy area, the fact that the room is on the inside facing a courtyard makes that street noises are so subdued that it's hardly audible.
Overall: we had a great stay and would recommend it to any couple, any age. Just make sure you can climb a few stairs. But Hans is always there to lend a helping hand.
