I spent three days in Amsterdam and I found this b&b really nice and confortable. It's located in a safe and lovely area in front of a canal and near by the Van Gogh museum.
Irene the owner was really helpfull, she could give me lot of advices on publics transportations and on what to visit in Amsterdam. There is also a lovely white cat which is living there, so then pets' lovers would be enchanted
I recommand this bed and breakfast.
