The same way as, e.g., a generally beautiful life gets 'diversified' with pesky little problems and uninspiring invaders. The trick: keep things in perspective and look into the horizon.
For another easy example of such nature's beauty and soviet ugliness combination, go and have a look at the beaches of Yalta, Ukraine, where dysfunctional inelegant iron & concrete objects will remind you of the relatively recent proletarian past.
True, some people do find socialist aesthetics exotic.
Put some music on. Train Sofia-Plovdiv.
