Without subselect, perhaps a JOIN will do:
SELECT hotel.hotel, hotel.hotelid, hotel.price, hotel.star, place.place
FROM hotel
left join region on hotel.idregion = region.idregion
left join place on hotel.idplace = place.idplace
left join review on hotel.idplace = place.idplace
WHERE place.idplace = '$idplace'
AND (review.approve IS NULL
OR
review.approve<>'y')
