 Nothing at all I highly recommend it and will be back when I next visit Amsterdam 
 In addition to a perfect location and deeply comfortable room the Toren staff are unbelievably well informed hardworking attentive and thoughtful They even persevered until they sourced tickets for the Ann Frank house until they found them for me They cheerfully booked taxis a canal cruise and brilliant local restaurants they recommended In a foreign city for a short time this is exactly the expert team you want on your side ensuring you make the best of your time Make time to get a cocktail or delicious gin and tonic in their outrageously flamboyant bar
