Just outside the entrance to Acropolis subway (metro) station, it's a quiet spa, at sub-street level. The people are delightfully friendly and welcoming. They know their stuff and the experience is just what you expected from a place like that. You can arrive a few minutes early and enjoy your tea, get changed into a bath robe and follow the friendly staff to the massage room or the hamam. We had the whole body massage. They will ask you about your preferences to make the experience more pleasant and immersive. Once finished, you'll have the chance to relax for a few minutes, take a shower, have some more tea and traditional treats in the lounge and then get changed to your clothes at your own pace, leaving the place totally relaxed and rejuvenated. Many thanks to Stella and Sotiris for an excellent experience!
