Here's the deal ... Blueface just put his 3-bedroom mansion in the San Fernando Valley up for rent on Airbnb for a cool $2,500 per night, but there's a catch.

The listing says the host doesn't allow pets, parties or smoking.

Remember ... the rapper caught a ton of heat for hosting a party at his Chatsworth crib early on in quarantine. Video from the bash showed a bunch of women in g-strings and bikini tops getting into an all-out brawl.

Maybe Blueface learned a lesson and started listening to Dr. Fauci ... unlike some people.

Anyways, Blueface's pad looks super modern ... it's decked out with a pool, hot tub, indoor fireplace, grand piano, pool table and a basketball hoop.
