Learn Spanish (Latin America): ¿Podría decirme si la mensualidad incluye un cuarto amueblado? - Could you tell me if the monthly rent includes a furnished room?

Using the conditional podría (could) is a strategy to soften the request. It makes the question sound much more polite and less demanding than asking ¿Puede decirme...? (Can you tell me...). This kind of pragmatic attenuation is especially useful when speaking to strangers, customer service, or potential landlords.

Could I put the me before the verbs instead, like ¿Me podría decir...?

Yes, absolutely! When you have a conjugated verb followed by an infinitive (like podría and decir), object pronouns can either be attached to the end of the infinitive (podría decirme) or placed right before the conjugated verb (me podría decir). Both sound perfectly natural and mean exactly the same thing.

Since the speaker doesn't know what is included, shouldn't incluye be in the subjunctive?

No, because of a very strict rule in Spanish: you never use the present subjunctive directly after the word si (meaning 'if' or 'whether'). Even though there is uncertainty about the answer, you are asking about a concrete fact, so the present indicative incluye is the correct choice.
