The Marriott Renaissance is in a good location. You can walk to the riverboat and also walk down the Kalverstraat to the Dam Square, museums, canal boats, restaurants & shopping. The Red Light District is only about 3 blocks away. The hotel is 1 1/2 blocks back from the main street so it's very quiet. They have an excellent concierge lounge for those with the appropriate Marriott or Starwood levels.
