Thanks for the info.... And the 1869 map, which I hadn't found on that site before, and shows King Georges Court and helps place a few things.
The enumerator looks to have walked up Plaistow Road (the old one, now also Church Street), east along Church Street and down Abbey Road.
There are a number of Places and Terraces recorded and not that many actual addresses on the roads themselves, so yes looks like they listed the building names and not the street address:
1-5 Montague Terrace
9-1 Abbey Park Terrace
1 Marcus Street (2-38 - 18 Uninhabited, 14 Building)
1-3 Cedar Place
1-20 Nursery Terrace
? House
Providence House
Church Street
3-1 Prospect Place
26-24 Church Street
1-7 Curtis Building
23-1 Church Street
1-20 King Georges Court
Abbey Road incl Greyhound Public House
So looks like Nursery Terrace was probably opposite the Angel Pub?
