It all depends on how much you want to spend there are many different types of housing, there are long term rentals which is what I had when I was there, you need to google Amsterdam apartments and then when you go stay in a hotel for a little while and have someone show you all of the apartments in your price range. I would recommend the Nines area which is probably one of the nicer areas and you can get a great place that is already furnished for between 1500 and 3000 Euros per month depending on the size you need. I would suggest to find an agency and have someone show you what is available on your next visit, and then make a decision
