After looking around, I still think London 24fall should stay in 1b.

It means, it's still more comfortable to go for option 1b, the room is very spacious, with floor-to-ceiling windows in both the living room and bedroom 🪟. Utilities like water, electricity, and internet are free to use, and there's also gas available. As for furniture and appliances, basically everything you need for daily life 🈶️. And there's a subway station 🚇 and a bus stop 🚌 right outside the door. UCL/KCL/LCC/IC and even Queen Mary University are all reachable by subway.
