How we choose. We look only at the gym: size, free weights and machines, opening hours, extras like a pool or sauna, and what guests say about it. Categories follow the official star rating. Every fact comes from a public source listed under each hotel. Links to Booking.com are affiliate links: if you book, we may earn a commission at no cost to you.
