Amazing in how someone designed the refurbishment of this tiny historic building to maximize its comfort into a great hotel room! Attention to detail was impressive and effective! Little touches like providing terrycloth bath slippers to combat the cold tile floors, earplugs to combat the noise from outside, and two layers of curtains to allow the level of light and privacy a person could want was impressive! Bigger touches like the great mattress, pre-programmed tablet with local info, and seamless check in and checkout via my phone we're excellent. I can't say enough good things about this place, but there are some people who will not like it because of the unusual closeness to the public outside. Some people will not like having a busy city street directly on the other side of their hotel room wall, and some people will be nervous about feeling secure, but I had no such issue. I loved the feeling of being so close to the people of Amsterdam, taking pictures of the bikers and boats outside my window, but I recognize that no amount of excellent design could counter the nervous feeling I know some folks would get. But for those of us who crave an unusual experience in a beautiful, comfortable room made from an historic building, the SWEET Hotel system cannot be beat!
