I absolutely love the place, very nice facilities, lots of light in the thermal spa area and dark, calm, cozyness in the relaxation lounge. Not crowded, super clean, quiet and relaxing. The only flaw was that lower jets in the jacuzzi didn't work. It was still extremely pleasant to sit in.
Spent a great few hours at the spa London Wimbledon. Relaxing atmosphere, very friendly staff and perfect cleanliness. The body exfoliation treatment was amazing, left with super smooth skin. The spa facilities were all very new and in perfect repair, however they were on the small side with only one sauna and steam room each and no cold plunge pool to properly cool down in between. So it really is a choice between the nice intimacy at this spa or a wider choice of steam and sauna facilities.
