The location is convenient! The prices are average, depending on the size of the cell, which is very cool! If the luggage is small, then you do not need to overpay! There are additional services, but I did not delve into them, they seem to have a schedule on their website
I rate the place positively, they have an excellent website, you can calculate the cost of storing your luggage, the average cell will cost 4 zlotys per hour, you can also use various additional services, which is also a big plus
