Hi,
So this post is very concise. First, the opening hours, Second, how to get there as it is NOT indicated when driving.
1) Opening hours of the Royal Mail Delivery Office (Coventry South), located in Airport Retail Park,Off London Road, Toll Bar End, Coventry (CV3 4RR):
2) To get there,once in the roundabout (A45,A46,London Rd) Toll Bar End,take the exit to WILLENHALL, and in the next roundabout, take the second exit, even though there isn´t any sign to the Delivery Office. You´ll pass a fake-roundabout and at the end turn right and...there it is!
(In Google Maps shows in a green field, but now the Delivery Office is there.
