Excellent location, about a 12 minute walk from Centraal Station. Public transit is available in Dam Square, which is less than a 10 minute walk from Tahier's apartment.
Being right in the Red Light District, the area can be noisy at night, but it did not keep me up.
Tahier was a great host and I had great communication with him. His neighbor, Regina, was available to let me into the apartment right away.
