Getting to the apartment from AMS Airport: We took 397 bus - half hour. A Short walk and you're there.
Getting around the city: There are multiple trams within 1 min walk from the apartment. This is a great location. Walk to Anne Frank house, canal boat tours, many many restaurants, etc.
The Apartment: Clean, super- friendly hostess, interior stairs connect directly to host's apartment. Tram noise is loud in front bedroom, quiet in rear bedroom.
All in all I would definitely stay here again, but it would be better suited for 3 or 4 guests. It was a bit tight with 5 of us.
