We went as part of a hen party, it was really nice and relaxing you can pad additional to have a massage done too... I would say 2-3 hours is more than enough time to spend there.
Amazing morning very relaxing and peaceful environment. Had massage which was good but wished I'd had a longer session ,all good on this trip ! Would recommend just getting a taxi there as all uphill and only cost 5e from adjere
Well worth the money for the time you spend there. Do yourself a favour though and don't walk there like we did as quite difficult to find - although it made us want the spa treatment even more! Take your own towel, robe and indoor flip flops though or you have to pay more money to hire them oh and you'll need a euro for the lockers. The staff spoke perfect English so no issues in understanding what they were saying when explaining the spa. For an extra cost you can get a massage but the water did the job perfectly and we both felt very relaxed afterwards.
