In Club World I don't think you can improve on this. These seats are in the forward mini cabin, with just 2 rows of seating. So the usual problem with the aisle seats - being somewhat exposed on the aisle - is mitigated by the lack of footfall and the fact that there is only on row of seating in front. The window seat is very private and with direct aisle access, as you indicate, and is a safer selection than 7K since on longer flights that would be designated as a crew rest seat, hopefully that's already blocked off but sometimes they are slow to do that.

As a single traveller I try to get 7A on this aircraft. If I was deliberately trying to find fault with these seats I guess I could point out that when the overhead lockers are open the cabin feels fairly cramped, there is a bit of a feeling they squeezed everything into the available space, though it is the standard CW seating. Also there are 2 windows on 7A (some CW seats such as 13A have 3 windows) and to see out of the nearest window means either pressing the Bolt Upright seat button or by perching forward. Anyone under about 1m70 / 5ft 6 may find it a bit uncomfortable to be look out of the windows for any length of time. On arrival into LHR it's a 2L exit, so if you want to avoid daggers in the back of your head on arrival, get yourself fully packed at "20 minutes to arrival" so you can glide off quickly (pet CWS annoyance is to see people surprised to have successfully landed at LHR!). The aisle is too narrow to let people pass around you. Service is delivered by the CSD/CSM in that seat.

I hope you have a good flight and you will let us know how it transpired.
