Carol's flat is in a very good position to explore the best places in London (from the near King's Cross tube station each angle of the town can be easily reached). The room is quite pretty and we felt very comfortable during our stay, the only negative point were the draughts from the window: they made the room quite cold. However, the duvet was enough to solve the problem. The rest of the flat is pretty too, even if the bathroom wasn't as clean as I expected (especially the wc and the floor). The girl who welcomed us, Itziar, was so kind and ready to help us in everything we could need, she left us leave our luggage in the flat even after the check out time and we had a very good communication. The overall feedback is positive, Carol's flat is a nice solution if you wanna explore London without being far from the town center and without spending a lot of money. I'd definitely stay there again.
