Mark is fantastic guy ! The communication with him is excellent, we were greeted warmly and we could store our luggages before the check-in time and also next day (after the checkout). We didn't know that the breakfast was included in the price and even though the breakfast was modest we were satisfied as we could eat something and drink coffee before we set out. The room were clean and beds were comfortable. The bathroom was a little bit dirty.
Anyway, the best price to quality ratio in London !!
