Is the Mira Bar Cart good for a small apartment?

Yes, if you keep it in one spot. The round footprint fits corners and tight walls, and the two tiers hold a compact bar. It is heavy once loaded, so plan where it lives before you fill it.

How does it compare with a rectangular metal bar cart?

It trades flat shelf area and easy rolling for a sturdier, more decorative build. Rectangular carts hold more bottles and trays; the Mira looks more like a piece of furniture and less like a service trolley.

Can the cast glass shelves hold heavy bottles?

The cast glass is thick and rigid, which is the point of the design. Distribute weight across the shelf rather than stacking everything in one corner, and keep heavy bottles on the lower tier.

Does the dark glass make the cart hard to keep clean?

The brown tint hides some marks but shows dust and fingerprints in bright light. Wipe the glass with a damp cloth and dry it to avoid streaks on the dark surface.
