Great spot, lovely venue. I had booked a spa afternoon with afternoon tea for me and my partner as a birthday treat. This was to include full use of the spa facilities, gym, sauna use of the Hamam and a 45 min massage each. When we arrrived there was no spa staff...we had to wait for them to arrive to switch on the Hamam and sauna. Also the shower was blocked (I had to use the mens). When the staff did arrive because they were running late we did not get to relax and enjoy the sauna and hamam and the massage - it all felt quite rushed. It was a shame that the staff were not a bit more organised which made it feel not great value for money.
The Good Spa guide calls Le Kalon "sophisticated seclusion" and I tend to agree. I've been to quite a few Spas before and tried lots of different treatments, so for me it's more about discovering great new venues and feeling like I've found a little haven not everyone knows about. Le Kalon is just this ... it's located inside The Bentley Hotel in swanky Kensington, and has much more personality than many hotel spas.
