Before I tried the Buff Day Spa, I had walked past it a hundred times without noticing it was there.
Its unassuming door is tucked away on South King Street, just down from the Gaiety Theatre, and opens to reveal a narrow staircase.
Once you get upstairs, though, you're in for a surprise.
It's SO much bigger than you'd expect, with various treatment rooms, a sauna, a relaxation area and a tranquility room.
It's all beautifully decorated and so quiet it's hard to believe you're just a few metres away from the busy street.
Some of the treatments are a little pricey but the beauticians really know what they're doing and are all lovely.
You can also spend as long as you want relaxing there afterwards - great for getting away from the world for a few hours.
It's a thumbs up from us!
