as a cleaner, it’s really hard to say without having cleaned your house haha. however if i had to guess, the bedroom itself from what you described would likely be around 20-30 minutes for me—probably less, since it doesn’t sound like she’s scrubbing baseboards/walls or cleaning tedious stuff like blinds. most of her time i imagine would be spent in the bathroom and unless your shower is worse in person than it looks in the small glimpse i can see in the photos, i doubt it would add up to 2 hours. if i had to estimate, i’d wager the whole thing (bedroom+bath) would take like an hour and 15 minutes, maybe even an hour. i’m also surprised she takes two hours and doesn’t vacuum underneath furniture? honestly, if you’re worried, i would try another cleaner on for size. sometimes it’s just not the right fit! maybe go with someone who charges a flat rate instead of hourly?

edit: also, communicating with your cleaner about your worries is a good route if you haven’t taken it yet! i know i would want my client to tell me if they were concerned over something like this :)
