It's already been a week since I arrived to London. It's certainly a massive change coming from a small city to one of the largest cities in the world.
I'm living with a host family in Croydon, just to the South of the center of London. It's a residential neighbourhood, so it's very quiet at all times. Also very convenient, since my commute is around 30 minutes long.
I work in a small office located in a big business center just by London Victoria Station. It's part of a company based in Madrid, so there's plenty of Spaniards around. I am also given a lot of freedom regarding any improvements I can think of during my work.
About the weather, there's really no way to predict it. It can switch from very sunny to very rainy in the span of a couple hours, so carrying an umbrella is mandatory.
Still a long time to leave, lots of time to explore.
