Outgoing professional looking for a room

Hi, my names Ernest and I am a 24 year old professional. I just finished my master's degree in Madrid and re-locating to London I'm outgoing, sociable and do a lot of sports. I enjoy going for drinks/dinners with my friends and have quite an active lifestyle going for walks, runs and playing a lot of sports. I am looking for a room with a single or double bed but preferably en-suite. I want a social life in the house not just flatmates that stay in their rooms 24/7.
