Crosby Terrace Guest House 1920's

[olduser1]

As soon as the 1921 census became available i found yet another twist into my relatives movements .
In 1921 they took a well earned holiday on the IOM staying with Mrs Edith Quaggin at 5 Crosby Terrace.
Can anyone help identify the location of their guest house ?
Any help or suggestions welcomed.

Now traced to somewhere along of Ballaqualye Road, I know there is the old Post Office Crosby terrace must be that end of the road .
Any ideas for confirmation of  5 Crosby Terrace welcomed
