I liked Amsterdam
Arrived in Amsterdam for the Buiten Westen music festival. Amsterdam is very convenient to get around. Lots of trams, buses and night buses. Very safe! I found the people polite. Many instances of being very helpful, some instances where it was better not to ask. If you don't speak Dutch, many ND's speak English. But do your homework and know where you want to go. Google maps was not up to date and the bus references were not correct. Over-all, I want to return for a longer stay.
Insider Tip:Like London or Paris, its not important to stay in the center of town. The transport is that good, (tram, buses, intercity train, night buses) moreover the suburbs are calming. Downtown can be very packed and its nice to stay in lodgings out of the way. Its easier to get form one tourist spot to the next than London or Paris.
