Positive. On the second floor there is a large hall on two levels. Good ventilation, as the hall is huge. There is a judo hall on the third floor. It's a pretty nice, small room, with a small locker room and a shower room. The elevators are all in working order. On the ground floor there are coffee machines and vending machines with sweets. The building itself is located in the city center, with a good transport interchange.
Minuses. Everything in the halls is a bit outdated. Benches, mats, etc. You can only go up the stairs to the judo hall on the third floor, the elevator does not go there (or so we were told). It's a little difficult to get up with a stroller.
