Mixall studio presents a good solution for your games, VR projects and simulators: LOW POLY WORLD - HOSPITAL.

Character setup to work with Mecanim (no animations included in this pack). This pack you can optimize and use to create games, simulators and virtual reality projects.

You can play a FREE DEMO before purchasing. Since the WebGL version is limited, the textures are different from the original and are highly compressed. It's also worth waiting a bit for the project to load on the web, that's fine.
