The space station in Earth orbit has one big problem: radiation. It'll require a lot of shielding to be safe for long-term habitation.
This is one reason why space stations for long-term habitation aren't a great idea, and why building long-term basis on asteroids or low-mass moons (e.g. Phobos) is much more viable, since you can just bury your habitat in a couple of metres of regolith and have all the shielding you need. For short-term habitation, low levels of shielding plus heavily shielded "storm shelters" on spacecraft and stations are a reasonable approach.
