From the Airport take the train to Hoofddorp (at first stop leave train). From Hoofddorp train station it's a 8-10 min walk to accommodation.

Buses also run from Schiphol airport to Hoofddorp.

And there are buses at Hoofddorp train station.

Get off the bus at the first stop past the Hoofddorp Trainstation (this stop is called Nieuweweg, ask the busdriver to stop there) From there it's just 1 minute walking to your accomodation, near the roundabout.

And (more expensive): taxi's ofcourse.
