While the Marriott Serviced Apartments have been pretty hard to miss since they opened over a year ago on the high-end Sukhumvit Soi 24, you probably didn’t know that the towering twin buildings have also been concealing an impressive health and recreation club. Reopened in August after a repaint, the best bit is that anyone can walk in (well, as long as you pre-book) and use the three brand new badminton courts, two squash courts and a billiards room (rates start from B250 an hour) or enjoy the health club’s gym, Jacuzzi, pool and steam room (B500 a day—monthly, member rates also available). The highlights, though, have to be the rooftop tennis court and golf practice center, perched on the 11th floor. And before all you sporting amateurs start with the excuses, you can hire all the equipment kits you need for any of the available sports, for free—as long you don’t end up smashing up your racquet in a fit of pique on their pristine Astroturf.

Health Club open daily 6.30am-10pm; recreation area open daily 7am-10pm
