Unable to answer "What’s the house number of this building?" for https://osm.org/way/83630366 via StreetComplete 46.1:

The address of this is 
"Holiday Inn Express Edinburgh - Leith Waterfront, Britannia Way, Edinburgh, EH6 6JJ United Kingdom".  I don't think it has either a number or a house name.
