Response from Willem:
See the Review below about communication and other Reviews - you have to see this one in the context of those.
Check out is clearly stated as 11am. It is occasionally possible to leave luggage till later in the day, but if the apartment is booked by someone else that same say, it is virtually impossible to make such an arrangement as it would be a intrusion on the next guest - who would have someone else's luggage in the apartment. Further, this guest did not ask in advance to leave luggage.
As to left luggage facilities - this guest left on Boxing Day - sadly, the station at Charing Cross was closed that day, like all other London Stations - there was nothing I could do about that.
All of that said, I am really sad this turned out to be less than my guest hoped for but as for Julian and Raquel, the couple who look after the accommodation, there is continually much praise for them - I think they are jut great, as most people do.
