Jackie O studio was as good as described, nice and clean, and has everything you may need during your stay. And the studio is located in a nice area surrounded by canals and the view is beautiful, while the location is great for getting around.
Jackie is very thoughtful, she provides everything even including eye make-up remover. She is very responsible and responsive. When we checked-in, she was there greeting us and provided us a pile of information from sightseeing to restaurants. She was very considerate that she worked with us to bring our heavy baggage up to her studio as the staircase is very steep and spiral. And at check-out, she came to help us as well.
Since we were studying for 4 nights, Jackie offered to change the towels and clean the rubbish bin in there middle of our stay when we were out.
She is really a great host, thorough, kind and thoughtful. I won't hesitate to stay at Jackie O again if I go back to Amsterdam. But do watch out your steps when going up and down the steep staircase which is the same everywhere inside the building in Amsterdam.
