Narrative:

Taxiing in to [gate] we briefed the arrival; approach and taxi plan enroute. Taxiing in to the alleyway the 10-9 and 10-7 charts show [gate] on the left side of the alley next to [gate]. It is actually on the right side of the alley next to [gate]. Certainly the diagram gets you to the right area but the alley gets very space constrained with aircraft and construction equipment so the last minute change to the taxi plan caught us off guard.
