So its minimum rental length is 30 days; that's $3,270 plus 10% state tax, plus hotel tax, plus cleaning fees. A regular one bedroom apartment in Costa Mesa is at least a thousand dollars less (a quick search reveals places available for between $1600 and $2600).
There is no way Ryann can afford this place - and it's clear it was a short term thing, because she hasn't booked it for September. Someone booked her for two months; I wonder what she's going to do when she has to go back to Jolene's place and can't play pretend anymore.
Edit: just some quick math, adding in the state sales tax and an estimated $150 AirBnB fee takes her to ~$3747 / month, for two months is $7,494.
I hope for Bowie's sake she wasn't stupid enough to pay for this two month temp rental herself, because the cost was more than enough to cover a first-last-deposit on a place of her own for them.
