No there is no gym, but the hotel is realy beautifull!

Agree about train to airport. Be careful of taxi. They will cheat you. I arrived late in the evening so decided to take a cab. I researched prices ahead of time and followed instructions to ask the airport taxi attendants outside about an estimate of cost. They waved me off and told me to ask the taxi driver. They rushed me into the cab as if there was a line. Cab driver never gave me a direct answer. He didn't use a meter and I kept asking what the cost was going to be. He pretended he didn't understand. I could see the tracking on google maps and on his dashboard, and he took these long routes that were even far off for the construction nearby. Charged me 80 euros. I was really upset. but it was my first time back in Amsterdam after many years and I was starting my vacation so I just let it go because I didn't want one a****** to color my whole experience negatively. Luckily, the hotel experience was amazing and the train is really easy to navigate.
