Simulations of the formation of late-type spiral galaxies in a cold dark matter universe have traditionally failed to yield realistic candidates. The successful formation of Milky Way-sized disks requires the correct treatment of complex baryonic physics at sub-grid scales, particularly gas cooling, star formation, and supernovae feedback. In this talk, I will review some of the challenges involved in forming massive disk galaxies and I will present "Eris", a realistic late-type spiral galaxy formed in a high-resolution cosmological simulation. Eris appears to be the first cosmological hydrodynamic simulation in which the galaxy structural properties, the mass budget in the various components, and the scaling relations between mass and luminosity are all consistent with a host of observational constraints.
