We had a wonderful stay at The Boathouse. The location is very good, it's in a busy part of town, but not too busy. The room faces a quite street, so despite being on the ground floor it was quite. There's a very nice little cafe around the corner also. Our only interaction with Karen was when we first met and she handed over the keys. She also pulled out a map of the area and pointed out things and gave us the lay of the land. She let us know that she was available should we need anything or have questions. The room itself is cozy and comfortable with a private bathroom and its own entry. There is tea kettle in the room but no other kitchen stuff, but there are many, many restaurants all around. We made good use of the bikes, riding them to the museums, it is definitely a big bonus that they're included with the room. Walking and biking is the best way to get around Amsterdam.
