"Slaters Diectory of Manchester & Salford 1886 Alphabetical part 1 and there on page 435 are the sisters as Householders living at what looks like 158 Hendham and Queens Road.

Hopefully this will show the address is  113 Hendham. I can`t find it on the 1881 census showing Job Page, maybe it`s on another schedule
In the 1879 Slaters , an Ann Mangnall householder is living at the same address. 
I can`t find her anywhere else. 
This is all I can find on Warwick St, sadly no name to apply to.  
Liverpool Mercury Saturday, October 2, 1880
To let  house and shop. Apply on the premises 76 Warwick Street Toxteth.  
Whether this is the same address I don`t know . 
Liverpool Mercury Thursday, August 13, 1885;
Wanted respectable girl accustomed to milking 
76 Upper Warwick Street Toxteth
Liverpool Mercury etc (Liverpool, England), Thursday, September 9, 1886
As above
Not much help I`m afraid
