Location: Very central, Bus 159 and 59 are frequent and will drop you at the Trafalgar square in 30 minutes. The Victoria line tube is a short walk. There's a really nice market with all sorts of food from around the world, right next to the tube station. Also, I found the area as pretty safe.
Accommodation: A decent size room with a balcony, you get a cupboard with enough hangers, an iron, a double bed, a table lamb, a small fridge, and even shampoo and toothpaste which is really handy.
Host: A really nice and friendly person. Very quick to respond to messages. He gave me my own space and also shared tips regarding bus routes and places to eat.
Overall amazing value for money and a nice experience. highly recommended.
