Hello Brenda,
Yes, other hosts can see your review after the 2 week time period or once both guest and host reviews are complete.
You say you're a new host, and your listing mentions your proximity to University. I'm also a host in a major college town and have hosted hundreds of guests. I have instant book, and don't bat an eye to guests with less than perfect reviews or newcomers, because I can count on one hand the truly 'bad' guests I've encountered, and with some experience you will be able to see that as well.
Personally I only leave a negative review if there is damage, but we're in a highly competitive market and I'm thankful they're choosing our listing out of hundreds in the area.
Also, place yourself in their shoes...families who need to feed their kiddos in the morning while trying to rush and clean before check-out, people who need to get to their next travel destination, or perhaps their cleaning practices just aren't as high as yours, etc...
I would recommend raising your cleaning fee (within reason) or absorb it into your nightly rate, to a cost that will cover the average guest, plus a little extra for those times where a guest has left you with a less than ideal situation.
I'm lucky to have a high occupancy rate and wonderful income because after much experience I've learned to relax and not 'helicopter host'. Clean, reset, onto the next guest. Happy Hosting!
