London Dog Island sublet, 300 per week.

Sure thing! Here's the translation: "I'm helping my senior sister sublet. Photos are genuine. One of the rooms in 3b1b, 300 per week. Roommates are Chinese, with air conditioning. Located on the 19th floor, with great views. The building has a gym and 24-hour security patrols. It's a 3-minute walk downstairs to the Canary Wharf subway station. Whether you're working or studying, short or long term rental is 👌."
