Been here a full year now. Some fine-tuning occurred since joining 8/2015, thus the five stars. I looked at several clubs and with Base, there was no pressure to sign-up. The membership director, Cesar, even let me come in to see over a few days versus one work out (like other clubs). They also honored a special that had expired the previous day. This integrity put me at over 50% probability of joining.
In terms of pros: gym is indeed one of cleanest, if not THE cleanest I've worked out in. There is a lot of high quality, latest/state-of-the-art equipment. Stations/areas can naturally get crowded at peak times, but manageable. Broken equipment is fixed within the hour, unless a special part is needed. Weights are put back into their areas fairly quickly by staff if members leave about. They have an area for "BaseCamp", which I compare to a CrossFit kind of training area, and is very useful if you are training for ToughMudder or Spartan Race kind of stuff. I've not taken every class, but the ones I have are excellent. I've never felt uncomfortable for not knowing a yoga pose or how to adjust the spin bike; the instructors actually go out and show you how to do it (as opposed to shaming you). The owner is frequently on site and listens to feedback from members, no matter how asinine it could be. He increased amount of equipment and created more space based upon member input; he also put in teakwood showers and lockless lockers based on feedback. As for personal training, want to mention I was skeptical of my trainer when I signed up for it, and when I showed up, BASE had fired him before I'd started, assigning me to another. I mention this fact because they were 100% transparent, which is important in terms of ever feeling screwed. Training itself? I had an excellent trainer name James who gradually made me stronger and faster. There is an excellent juice bar/snack bar, as well as on-site BaseBody Spa and a doctor/nutrition consultant office on-site. Base also provides for two free hours of validated parking in the garage next door. Finally, Base has an app that sends notifications about class cancellations, hours, etc.--which is actually quite useful.
The cons: Mostly 1st World problems....no more sliced lemons or cucumbers in the ice water dispenser. Does make a difference between and upscale and meh atmosphere. Fewer towel racks, thus fewer towels available. Removal of one counter in locker room makes the remaining two more crowded. Wifi needs to be re-calibrated or upgraded to meet peak club usage demand. More cognizance of people spending A LOT of time on phones while at a machine whilst others are waiting. I can take care of that myself, but would be useful to enforce as a policy and not let it escalate between members. I've had a couple of problems with the garage staff and validation, security, etc., but that's not really a club problem. Just beware if you park there--like anywhere else.
Overall, I recommend Base without reservation.
