A nice thing to do when visiting Amsterdam during the weekend is to find a chip place where to stay. Actually, the city is full of temporary accomodations.

One thing you should be always aware of, is to not be scammed by people promising things and requesting money in advance. Also, you should always ask for a signed receipt when you rent temporary an house from a landlord, so that you are insured by the law if someone try to steal your money, giving you nothing.

The best places to look for cheap apartments for weekends are the following :

Amsterdam House

It provide a good compromise between price and quality and they are pretty clear about the service that they are providing you.

Frederik Park House

This is also a nice apartment where to stay if you think to come over with some friends (because the price is a bit high).
