Is there an easy way for foreigners to find a monthly rental studio apartment in Itaewon?

Hello! It's been a year since I came to Korea, and I'm currently trying to find a monthly rental studio in Itaewon, but it's really difficult ㅠㅠ Being a foreigner, I often get rejected by real estate agents, so I'm worried. Does anyone have a similar experience? Do you know of any real estate agents who have good tips or recommendations for foreigners looking for a studio in Itaewon? I've tried using the Zigbang app and visited several real estate agencies, but it's not easy. I would really appreciate any help! Please recommend good real estate agents or apps. Sharing your experiences would be a great help to me~
