Sports facilities split into two rough camps: welcoming to beginners, and built for people who already know their way around the equipment. Before you walk into ERG Sports | İstinye Tenis Kulübü | Yaz ve Kış Okulları in Sarıyer, figure out honestly which camp you're in — new to the sport and everything feels intimidating, or years in and a basic setup feels thin. Pick based on where your own experience actually sits, not on what the name promises.
