In Belgrade at that time, the International Book Fair and many hotels were already booked. It is the same with Hotel Serbia, which is the closest training site. That's why I give you hotel information in the surroundings and select one of them yourself. At Google you can see that they are not far from the Sports and Recreational Center Šumice, Ustanička 125, where a seminar is held. Contact these hotels and find the place. It would be good to book now. I think it's the best and I'm glad to see you on tatami.
Best regards, Mirko
