I was trying out at this gym when I visited London two weeks ago.  The location is very convenient.  Being a General Manager of a global service management company, I could feel everyone was so naturally nice and friendly to welcome you when I stepped in.  I have been Equinox for years, but I love the cozy and warm feeling at this gym.  You can really focus on your training without distracting from anything else.  The personal trainer, Mike, really helped me to engage in the program particularly designed for me during the three sessions.  I had a such solid training and wonderful experience at this gym.  I highly recommend it and definitely go back again when I travel to London.
