We stayed 4 nights at Arne's place. It was very easy to get to from the airport following Arne's instruction- we suggest going to the ticket counter and buying your ticket off them as the machines will not take MasterCard, visa or notes. The metro/ bus/ tram system is different to the train system so we also suggest that you purchase a 24/48/72 hr ticket to make the most of your time in Amsterdam. Outside Arne's apartment was a bus stop which took you right into the centre of town within 25mins and we had no problems finding our way around and using the public transport. Arne's apartment is very clean and tidy and we barely saw him due to his work. When we did see him he was happy to have a chat and help us out. There is a supermarket below his building and plenty of places to get food. Overall, we enjoyed our stay with Arne.
