Ask HN: Do you write Airbnb review frankly?

Right now, I am living in a house I found on Airbnb. The host is very nice and the housing is very good. But not everything is perfect. I feel it's hard/embarrassing to write something not good because the host is so nice and exposing that might affect her future rental. Not doing that might be not fair to future renters. What will you do? Of course, this not only applies to Airbnb. But this is a little bit different from the amazon review where the connection between a product/seller and you is much looser.
