Sparta Gym shows 4.9 from 231 reviews, and its four written reviews split cleanly by what they're actually rating: three describe genuinely welcoming, English-accommodating kickboxing and Muay Thai training in person, while a fourth describes a completely different problem - not being able to get a response at all before ever setting foot inside.
In-Person Attentiveness, Confirmed Independently
Rishit Mordani's review is specific about how coaching adapts to non-Polish speakers once you're actually training: "Even as someone who can't speak Polish, the coaches, especially Mr. Krzysztof Olszewski, always pay special attention to me to make sure I understand everything." Makz, independently, describes the identical pattern: "Coaches are paying attention to everybody, especially beginners. Even if I don't speak Polish, they make sure that I understand. Classes are quite intensive, well prepared with a serious warm-up." Two reviewers, describing the same specific accommodation for non-Polish speakers, independently - a real, repeated signal about how classes are actually taught.
A Different Problem Entirely: Getting a Response Before You Arrive
Ilayda Ozkan's review, one star, describes something that never got as far as a training session: "So many foreigners mentioned this course as 'foreign friendly' and 'coach pays attention for foreigners.' I'm trying to get information about this gym and they didn't even respond and speak Polish even though I speak English. If you don't respond to mails or messages, what's the point of putting your contact information on your website?" I want to separate this clearly from the in-person accounts above: her complaint is entirely about pre-enrollment communication - emails and messages going unanswered, or answered only in Polish - not about the coaching itself, which she never experienced. Both things can be true of the same gym: excellent, English-accommodating instruction once you're in a class, and unresponsive administrative communication before you ever get there.
A Named Coach, Twice Praised for the Same Quality
Krzysztof Olszewski is the only coach named directly, and specifically for the same trait Makz describes without naming anyone: patient, individualized attention to non-Polish speakers. That repetition across two reviewers - one naming him directly, one describing the identical behavior without a name - suggests this may be a broader coaching standard rather than one person's individual style.
What's Missing
No review states a membership or class price. Nothing confirms whether the pre-enrollment communication issue Ilayda describes is a recent or ongoing problem, since her review is the only one to raise it and it's also the most recent.
Who It's Not For
Anyone relying on email or message contact before visiting - one recent reviewer describes exactly that channel failing her, despite otherwise strong reviews about in-person English accommodation. Anyone pricing this out before visiting, since no review gives a figure.
