To call the venue a spa is overstating the offer as it is just a corridor with two small rooms, one a shower room with steam functionality that 2 people can sit in and small rooms which is the sauna.
I had a 2 hour massage (1 hour massage + 1 hour facial) as a treat and it was fantastic. The therapist is exceptional. She's welcoming, really polite and extremely attentive. She checked not only whether the pressure of the massage was right and adjusted it, but also light, sound and temperature. It was so amazing that I think I dozed off a little at some point! I know where to get my next treat!
