We really think we provide the best co-working space in the region. Our offices are not too big, so they are less noisy and more convenient to focus on. Working hours from 9am to 9pm. Each workstation features a 32-inch IPS screen without exception, the most comfortable armchair for long seating, including mandatory back, leg and palm rests. We are located in the city center right next to Terazije. We provided shower facilities and more. Each succeeding day is cheaper than the previous one.
