Good location -
The apartment is a few blocks away from the museum square.
Further, given that Amsterdam is extremely popular and nosy, you will appreciate the apartment quietness.
Although the studio is small, it is very adequate for a couple.
One issue that some may have is the steep stairs to the 4th floor. That is the reality of most Amsterdam buildings. If that is a problem, which was not for us, you will be better off considering an hotel.
