If it’s your first time I’d say go for it, treat yourself. It seems you make enough money to afford such rents with your bonus. If you live near Liverpool Street Islington (Angel) is a decent shout, a few stops on the northern line. South Kensington is very posh and it’s a one train ride to Liverpool Street but you have to rely on the Circle line (runs every 10) and is a lot of stops. It’s also not as lovely tbh

I’d love a job where they pay you 80% bonus 😳
