Mark's flat is clean and warm but access is via very steep stairs -not good for those with small children or mobility difficulties. You will need to use public transport all the time to visit the main attractions of Amsterdam as the flat is in the suburbs, albeit quiet and pleasant.
The double bed in the small bedroom takes up the full width of the room leaving no space to walk beside the bed to the window to open or close the window or curtains. There are no bedside lamps so expect to clamber about in the dark when going to bed!
