The stay

Conference-scale Kensington hotel beside Gloucester Road Tube — useful if you are coming up from the South Coast by train into London.

According to the hotel’s official materials, the property offers around 611 rooms across Deluxe, Club, Executive, suite and accessible categories. There is a fitness centre and meeting and event space — the hotel states 26 function spaces. There is no swimming pool listed in the sources we used.

Check-in is from 3pm and check-out at 12 noon. For rates, packages and accessibility requests, use the official Millennium Hotels booking channels or call the hotel directly.

The casino

Integration is address-level: hotel and casino sit on the Harrington Gardens complex.

Grosvenor Casino (London–Gloucester Road) is listed at 4–18 Harrington Gardens, London SW7 4LJ — the same complex as the hotel (SW7 4LH). The operator is Grosvenor Casinos Limited. We do not publish a specific Gambling Commission licence number here; check the public premises register yourself.

Casino entry is for adults aged 18+ with valid ID. House rules, dress codes, opening hours and game availability change — confirm on the official Grosvenor page before you travel. Gambling involves risk of losing money.
