I have really enjoyed the facility. have been a member since August last year. Sonny Renneti is an excellent PT and we really enjoy the Pilates with Candace. All the spin and pilates classes are awesome. The pool facility is great too

"Sall is one of the best PTs I’ve worked with, and I’ve been training for years." I trained with Sall about 8-10 years ago, and when I overheard his voice at Third Space recently, I knew it was him. I’d been a member here since 2019 but never used PT now I’m on my third block with him. Sall gets what you need in your 50s: mobility, quality of life, performance. His corrective exercise knowledge is excellent, and he always asks three simple questions, “what are you doing, why, and what effect does it have on you? That makes every session make sense. He’s also flexible with my travel schedule, a big reason I moved to blocks of sessions. Highly recommend. @Richard (Third Space member since April 2019)

Having joined city club in January - honestly such a game changer having been a member of more mid level gyms in the past. Something that is quite clear is the eye for detail and constantly trying to improve the experience for members. I also love the vibe, closer to a members club - great for building a network of like minded individuals in London. I’ve never been one for classes but the quality here is second to none. Love the Hyrox 90 on the Saturday with Lauren / Ty midweek. Another stand out is how friendly and welcoming all the staff are - clearly everyone is trained and recruited well. Kamilla most recently often doing the late shift when I’m leaving the gym - so friendly and helpful. One bit of constructive feedback - when I submit online questions, some are not answered. Please also add a smith machine to city club - then it will be the perfect gym :)

I really like going to this gym. Kamilla at the front desk is always lovely, helpful, and friendly. Ezekiel is also always a joy to chat. Some of the other front desk workers…not so friendly or welcoming. So, Kamilla and Ezekiel are always a pleasure to see when I walk in. Gym is pretty nice, clean, and the classes are wonderful. Unlimited classes and multiple facilities with the membership is awesome, especially given the price. Would recommend!

If you’re somebody whose hobbies revolve around fitness & wellbeing, then this is the perfect gym for you. I used to go to PureGym prior to joining Third Space because I didn’t realise how much the gym environment could impact your willingness to go to the gym and focus on your health. Now I come here and sometimes spent 5 hours at a time on the classes, gym equipment, recovery, spa & cafe. I feel like coming here has completely switched up my fitness routine as I very often fit the gym into my schedule before I have plans, and the fact that you can comfortably get ready here and feel clean is a massive bonus. All of the staff that I’ve met so far have been so lovely, from the concierge team, to the cafe team, to the PTs & class instructors, even the cleaners! And special shout out to the cleaners because I literally see them cleaning non-stop, and it definitely shows with how spotless the changing rooms are specifically. The classes at Third Space are great value for money when you consider that usually in London you’re looking at £22-40 per hour for most disciplines, and as somebody that usually does 5 classes a week at other studios, I’ve managed to utilise the classes here really well. Third Space is actually the first place I tried Hot Yoga, Pilates, & Sound Baths and they are now my new addictions! I do aerial arts & pole outside of gym and the classes here have really complimented my training & conditioning well. The workshops I’ve attended have been so useful too, such as the ‘hot flexibility flow’ and ‘hip rehab & prehab’ workshops which are great for flexibility. I’d like to specifically shout out 2 PTs that I had complimentary sessions with, as they were very knowledgeable and helpful even just in the short space of an hour. Sall & Honor are amazing at what they do and both have great experience. The food & shakes in the cafe are sooo good too. Everything tastes fresh & high quality, and it’s really hard to resist grabbing something as you finish your workout. Get the Strawberry & pistachio shake but make it vegan!! 🤤 My only bit of feedback to improve is that the changing rooms have the air con blasting, which is not really ideal when you’re coming out of the pool area soaking wet and hot, so if that could be changed to room temperature it would be absolutely perfect! ☺️
