Simon mailed us excellent directions of the way from the airport to the apartment. In the apartment Simon's friend waited for us, he was very nice and helpful. Simon left us a lot of maps, "Time out" about Amsterdam, and keys to his own bikes for both of us. He sent us a message that if we need something, we are welcome to ask.
The apt. is beautiful, quiet street, and the canal view is great! big, clean and comfortable.
We didn't saw or heard the neighbors.
