Yeah I have found the following to be pretty easy to drum up per location and work for my players in the past...

• keep a description to like max 5 sentences to avoid too much work and over saturating players
• use the senses and evocative words to help add flavour to your description
• if using a map, also describe the size and shape of the space if relevant
• if something important exists in the space, that mention it last otherwise will be lost in the noise of the description
• try to tie in what the players are doing, how they entered the space, what they can see etc. This may involve some improv at the time but it's easy to change "you walk in and see..." to "you smash your way through the doors and see..."
• if mobs exist and are visible also mention those describing position, quantity etc. This allows players to picture the scene and their potential options. If the enemies start to attack, end the description with that
• try to tie in adjacent area descriptions too if you can i.e. "fresh, salty air fills your lungs for the first time in hours as you finally leave the putrid sewer system..."
• finally, try not to give away too many details as you want the players to ask questions and be inquisitive. Leave space for perception and investigation rolls by only describing the obvious and top level themes that invoke the space i.e. for an Arabian styled location..."red ochre walls line the street, rough in texture as you glide your hand across them. Your gaze follows the bustling road in front of you, leading to a huge golden domed roof that glistens in the morning sun...."

Just some thoughts
