Coming from New York where you can find a cheap and cheerful spa offering affordable massages all over the city. It was difficult to find a similar place in London(especially with the exchange rate back in 07! Eventually this spa popped up in my local town in Putney about 2 years ago offering 1 hr massages for a mere £35. It’s relatively no frills but the rooms are pleasantly decorated but the walls are relatively thin so you may hear scuffling from the room next door. There is a steam room and shower downstairs as an option but I hardly use it. They offer 3 different types(Swedish, Combo and Thai) but I usually go for the Thai massage because it really gets the knots out of your back. I think it’s a hit or a miss depending on the therapist you get but from my recent visit, it was definitely worth it.
