Traveller reviews
Rowan “Overall an amazing stay, beautiful space and lovely staff. Fully recommended.”
02 Feb 2026
Such a unique little spot. So cool to jump in the sauna and then straight into bed (after a quick shower of course)! Everything seemed really clean and organised, with a huge variety of lovely cosmetics to use. Also, the staff were so helpful and quick to reply to questions and help in any way they could.
Shihab “The team were friendly and accommodating. Sauna was top.”
