The bike works fine for what it is. Be aware that due to the design (no top tube), the frame is much more flexible than a traditional frame. I don't know that I would describe any form of the bike as "light", but compared to other step-through frames, it's probably a couple of pounds lighter.
That said, we own one (3 speed/coaster), and it is nice for just what you want: easy, short distances. Unless something has changed, it comes with a rack/fenders, too, which is nice.
From an assembly standpoint, they have so-so quality control (compared to main-line brands), so it is really one of the few bikes that I would say to get from a shop--then the QC is their problem, not yours. It was not uncommon when I was selling them (Biria, as a brand) to receive a bike with kinked cables, ill-fitting stems (kind of an important part, no?), and poorly fitting accessories (racks). That said, the company was easy enough to deal with, and would send replacements, but it's probably not something you want to deal with as a consumer.
