Planning trip to marrakech , scared of bad reviews

Hey! I'm planning a 6 day trip to Marrakech in March.

I was thinking of going to the waterfalls with a guided group, maybe do the mountains, go to the desert etc with quad biking and camels, and do hot air balloon. But I've heard a lot of bad things about the city and I'm not sure if it's worth going am I making a mistake ?
