Silver

Brilliant execution. And we’re picky.

Bronze

They did this well. You’ll notice.

Listed

A defining trait. Makes the hotel what it is.

The eight vibes

Built around a vision. Even the door handles have a designer.

Luxe

Cared for at every turn. The bath is drawn before you ask.

Local

It could only be here. You wake up knowing where you are.

Social

Where the city goes out. The bar is full and the night is young.

Heritage

A building with a story. Once a palace, a monastery, a station.

Wellness

You leave feeling new. Rest, sweat, soak and sleep like a stone.

Classic

The city grew up with it. Same rituals, same regulars, same bar.

Resort

A world of its own. Something to do from breakfast to nightcap.

The scene

Lively

Where things happen: restaurants, shops, people.

Central

Well-located: walkable to some things, a short ride to more.

Quiet

Away from the crowds. Getting around takes intention.
