We booked this flat during the end of May 2018, and it is the perfect distance from many amenities. Walking to the center was less than 10 minutes. It is located on the second floor and is very quiet at night and safe. We left the windows ajar at night for the night air. The WIFI is a great perk which helped with communications.
The title may say cozy, but it’s designed very well and offers so many comforts of hone that you won’t book another hotel in Amsterdam!
