I can't recommend Lorena's place enough! The location is fantastic, the tube station is just a few minutes walk away, as well as bus station. The place itself was very clean and cozy; fully equipped kitchen was a surprising bonus. The only thing one should be prepared for is a bit of noise from the street; as in all big cities, this is a (small) price to pay for being almost in the city centre. Though if you're sensitive to it, make sure to bring earplugs with you. We'll be definitely coming back in the future!
