I would hands down recommend Thedie's apartment: super comfy bed with view directly onto the canal, incredible location to explore Amsterdam, clean, tidy and modern, really easy checkin & out. Communication with Thedie was fantastic, he always kept us informed and sent us a list of fun things to do.
General advice for people visiting Amsterdam in the summer and staying in traditional single-glazed window buildings on the canal...take ear plugs, the seagulls are really loud in the mornings!!
