London Rentals | Why is there such a big difference in the same type of rental?

I booked a 20-square-meter studio, thinking it would be like the first picture, but when I arrived, I realized it was actually like the second picture! ‼️ I feel like I've stumbled upon a hidden gem. 😍 The location is in a wealthy area of London, next to the US Embassy and MI6, plus the apartment has its own security system. Who could feel safer than me?? It's only 350 meters to the subway station, and although it's close, the room has good soundproofing, so it doesn't disturb my sleep.👍 💎Within a 5-minute walk, there are Sainsbury's and Argos supermarkets (very large, almost everything you need can be found there). 💎Within a 5-minute walk, there are also two Chinese supermarkets. 💎Within a 10-minute walk, you can reach Waitrose and Tesco, as well as Starbucks and Pret A Manger. 🌟There is air conditioning, 🌟there is a TV, a double bed, private bathroom, desk, wardrobe, microwave, stove, and refrigerator.
