I would not recommend you to join the gym as this gym probably has old set of machinery and If you have to spend more time on cardio exercises then this isnt your cup of tea as still old non functional trademills are used and even trainers there have left the gym. But talking about the spas, these are good enough and there full body massage is awesome.
Also they do not provide with fresh lime water, lemons are mostly rotten and even coffee machine is also sometimes broken.
