I've been to multiple concerts here: George Ezra and Central Cee. It's on a very nice location at Leidseplein. Also been to a couple of club nights. They have strict security yet friendly staff. I 100% recommend going here for concerts as they have a good air conditioning/circulation system and the music quality (sound system) is nice.
They have lockers and a machines where you can pin for a coin for the locker.
They have plenty of toilets!
They have plenty of bars therefore you have your drink quickly.
You can smoke outside (without exiting the club night)
