nifty Hogwarts facts/which floor?

Here's a couple of tidbits that I figured out recently. (I know, get 
a life...)

The lake is to the south of the castle. (In PA, as the kids tried to 
find North Tower for their first Divinations class, they knew they 
were going south by mistake because they could see the lake out of 
the window)

The front doors (double oak, BTW) face more or less west. (As they 
wait to exit to castle after having used the Time Turner, the setting 
sun slants in the open front doors).

But here's something you British folks can help me with. Because we 
Yanks refer to the ground floor as the first floor, while you Brits 
call the floor ABOVE the ground floor the first floor, it's a bit 
tricky to place some of the rooms. Could you tell me where Moaning 
Myrtles' bathroom is? I place it on the floor you get to when you go 
to the top of the marble staircase (second to Yanks, first to Brits). 
Does that make sense? Also, do the British versions refer to 
Gryffindor tower's common room as being on the seventh floor, same as 
the American versions? If so, I'm going to assume that means the 
BRITISH seventh floor. I'm trying to create a concise list of which 
rooms are on which floors and this whole first floor/ground floor 
thing keeps getting in the way...
