Take Metro 52 (direction station Zuid) to Station Vijzelgracht.

Once you get out of the metro station Take Tram 7 (direction Sloterpark) or Tram 19 (direction station Sloterdijk).

For both trams the stop for you to get out is Leidseplein. (From the metro station it is about 10-12 minutes by foot to the hotel should you prefer)
