Looking for nice accommodation and flatmates

Hello, I’m freelance makeup artist. I’m just moved in London, can speak simple English. Sometimes will have different people visit me, I believe not very often. I’m easy going, clean, quiet person. I looking for quiet, no smoking, friendly and clean environment at the same time I don’t mind and happy to join the party/ activity/dinner with flatmates. Also can explore outside together. I wish the accommodation near the underground or have good transportation connections that I need to carry my suitcase to go to work mostly. Thank you:)
