I visited Wayang Center in Lisbon during my last visit to Lisbon-Portugal with my wife.
We wanted to try a Balinese Tantric Couple Massage. We visited this SPA and it was truly an amazing experience. Good therapists, Good Massage and a dedicated couple massage room that you only find in 5 star hotels.
Great service! I do recommend. Here is the link: https://massagem-sensual.com/en/
