But what about the risk of missing things that only show up under that strong light?

Ever try calling places directly instead of just looking online? I had that happen in Barcelona once, and I ended up just walking into a few hostels to ask at the front desk. Sometimes they hold back a bed or two that isn't listed on the booking sites. Also, check smaller local sites instead of just the big global ones. I found a spot in Rome on a site I'd never heard of before. It takes more legwork but it can save you.

Photos are the best teacher, right? It's like trying to explain to someone why you don't pour cold water into a hot glass dish. They won't get it until they see the crack. Your photo is that crack. Let the dry air do the talking for you.

Guess I overcooked my chili for years, thanks @zara_hill46.

Ask for a picture, like @jesse4 said.
