We have a large two-story appartment in the heart of the city. Just around the corner from the Anne frank house and the westerchurch. We sometimes rent out the entire appartement (€175,- 2 double beds), and sometimes just the double bedroom (€85,- ) and share the kitchen/livingroom with my housemate (or me!).
Very accessible with public transport. Its an 8 minute tramride to central station (tram 13 or 17), stopping 50m for our doorstep at the Westermarkt. Train ride all day and night to and from Schiphol airport.
