Hi Emilia,
how are you? I've been hosting since June 2018 and this is the very first time I've clicked on the "Community Center" link. Please forgive me if you're wondering what my upcoming query has to do with this particular topic. You seem to be a knowledgeable/ experienced host, so, instead of calling the airbnb Superhost hotline, as I'm wont to do, I'm "(ab)using" you :-). Here goes:
I'm a 4-time Superhost with 45 guest reviews...and counting. As a real newbie, I was once (deservedly) given 4 stars for "accuracy", So far, so good. All other reviews exclusively 5 stars until last month when a guest (most undeservedly) gave me 4 stars for location and value. My question is: why do 4 stars in 2 out of 6 categories warrant an "overall experience" of 4 stars?? That defies the laws of mathematics. I've seen half stars on airbnb. In case I get a response to this message, I thank you in advance!
