Overview

What this property combines for overnight guests

Millennium Hotel and Conference Centre Gloucester London and Grosvenor Casino The Gloucester share the Harrington Gardens address block (hotel SW7 4LH, casino SW7 4LJ). That shared street number is why the pairing qualifies for this guide.

The hotel markets conference suites, dining and a fitness room; the casino is a Grosvenor Casinos Limited premises under Commission account 614. Official hotel and casino phones differ — use each for its own purpose.

South Kensington’s museums and Gloucester Road station make this a practical base for visitors who also want evening gaming without a separate taxi across town.
