Karin was very accommodating during my stay -- making a point to meet me and turning up the heat when I requested it. She's also prepared a very nice booklet highlighting the restaurants and breakfast spots nearby which was very helpful. The flat was comfortable -- particularly the bed, and the location was very convenient. Being in the central part of Amsterdam and on street level, one should be aware of the possibility of street noise that sometimes lasts late into the night. But nevertheless, it is a convenient place to stay and I would not hesitate to return.
