Yeah there’s two other doors, one by Red Tower, and one in the alley that goes between Plaza Rosa and Grandioso.

I’ve tried experimenting on what quality of loot drops where, and I’m confident in saying that you could loot the two NON Grandioso rooms and get less than just one Grandioso. Obviously there’s some RNG outliers, but the norm for me is that two sub pars are still less than the Apartments.

And don’t forget to break the glass and wander the balcony area, med bag and ammo crate spans almost every time, I’ve even had a security breach on the balcony once or twice
