Visiting late December, queries about general tourism in Harbin

I'm thinking of going to that city in late December, but I only speak a few European languages. Is it easy to get around the city to see the sights for someone that doesn't speak Chinese? And how would I go about it? Also, is there good, inexpensive accommodation? Is it safe for a single woman to travel around this area? I've researched the main attractions, and it looks like a nice place.
