Kylie Jenner's Turks & Caicos Rental Had 23 Rooms!

Kylie Jenner rang in her 19th birthday in Turks & Caicos with her squad in a $35 million, 6 acre estate.

Kylie's rental was ridiculous ... 3 oceanside villas that could accommodate 54 guests.

2 of the 3 homes had 8 bedrooms and 8.5 baths, while the third was a bit of a downgrade with a mere 7 bedrooms and 7.5 baths.

Other perks ... a personal chef and butler, tennis court, 1,000 square foot gym, waterfall, Turkish steam room, sauna, massage room, fire pit, and kite surfing and snorkeling equipment -- all hooked up by Airbnb.
