We never saw Charles. Gisele was a great hostess very accommodating to our arrival time, the place is very clean and exactly as portrayed in the pictures. It's always clean as well as very closed to Puerta del Sol. The nature of the neighbourhood is a bit noisy (no fault to Gisele!), so if you are a light sleeper like me, you may want to consider this before booking it. Otherwise you are at a great spot with very walkable paths to all attractions in the city.
