The gym is small but has an amazingly wide range of machines. Dumbells are a bit limited but you can assemble your own if needed. Clean room and good music playing. Not crowded so no waiting to get through your routine. Bit pricey though, 13 euro for a day pass. But that's with everything on this island.

We've visited Mykonos for a week and pump@54 was a great place, conveniently located in town, where we could pump up before heading to the beach parties. Clean, friendly, nice!!
