Here is how the guest sees the breakdown for 2 nights, which is your minimum stay. Let us know if this doesn't answer your question (in other words, if the 150 per night is higher than what you intended).
The difference seems to be the number of guests. My screenshot is for 1 guest and I assume your host breakdown is also shown for 1 guest (150 per night).
I see that Shelley's already taken a close look at your pricing breakdown and it looks like things add up. Would you be able to let us know if you need any more help or if it's all clearer now please?
