Narrative:

Aircraft X was in route to stt direct to kutho for the ILS approach and descending to 2800 feet. There was a small patch of precipitation over kutho; and aircraft X requested to deviate south of it. The approach controller approved the deviation and instructed aircraft X to proceed direct jaqyy when able and advise. The approach controller then told aircraft X to descend to 2700 feet and report the field in sight for the visual approach. Aircraft X advised approach they were proceeding direct jaqyy. Approach asked if aircraft X could accept the ILS approach clearance over jaqyy? Aircraft X responded with affirmative. Approach controller cleared aircraft X 5 miles southwest of jaqyy at 2700 feet due to the minimum vectoring altitude. Aircraft X asked twice if the jaqyy crossing altitude was 2100 feet. The approach controller issued a new crossing altitude for jaqyy at 2100 feet. The aircraft landed without incident.the controller allowed the pilot to talk them into giving them a lower crossing altitude. The controller should have stated the restriction again and included the reason of the minimum vectoring altitude. If aircraft X could not accept that altitude; they would have advised and a new plan would have been made.
