In context of "Addresses" overlay for https://osm.org/node/11180688998 via StreetComplete 54.0:

This might be both 57 Woodville Road & 57 Melrose Street. The building is part of a Terrace on Woodville Road in which it would be 57, however its entrance is on Melrose Street, next to 59. There is no 51-55 Melrose Street. I love this.
