I've visited a flat/appartment in one of the Barbican towers. It was comfy, pleasant. The lifts and hallways were well maintained, well lit, generous dimensions (compared with many London apartment blocks I've seen). It felt like a "good" tower block, rather than a "bad" one.

The arts complex is amazing (slightly confusing, but very functional and fairly pleasant to be inside). The outside spaces create a buzzy calm.

I think it's an excellent complex.
