Clean, quiet, scenic location, 25 minute walk (with luggage) from Amsterdam Centraal Station (we're in our 50s). Also 20-25 minute stroll to Jordaan area, Anne Frank house, and another 15-20 minutes from there to Rembrandt House Museum.
So, all of Amsterdam is available on foot (or via one of the 2 bicycles Sonja offered, but which we didn't work up the nerve to use), along with a peaceful nights sleep, while staying on Tasmania.
Clear directions, prompt replies, and a binder with local tips on food and sights, as well as hints that boats make different sounds than hotels which was amusing, but useful for boat newbies.
Would happily stay again.
