 Cleaning every two days The day before arrival was taken from the credit card all the amount for 6 nights I think correct taking in advance only one or two nights out of six in the case of no arrival this was NOT my case if the room eventually left vacant is occupied by other customers 
 Good position just near Metro stop and Amstel railway station Very juvenile climate it was original to find a condom in bed for the first night Our room at the 11 floor had a fine panorama over the city Many facilities in lobby and a well equipped free gym
