We (Me and my Mum) really enjoyed the stay at Klass's apartment. It's close to the tram which leads all the way through the city center on one side and a stepping stone to the really authentic experience of Holland and beaufiful surroundings with windmills by the river on the way towards Harlem on the other side. The airport is 15 mins away and we could see the tower from our room! You've got plenty opportunities in reasonable distances there. Hiring a bike would be the best, to wind off, catch up some air into your lungs and make the most of it! Premises where kept nice and clean, beds comfy and I really appreciated the coffee machine in our room. Klaas also left the sign Happy Birthday for me in our room, as it was my 30th B-day, which was really nice of him.
