It sounds like you are quite overpriced.
Normally if you are priced a bit high you will get offers but under your expected value. If you are priced a lot over then people will see you as unrealistic and simply not bother making an offer.
It is a quiet time of the year though - people generally aren't into doing that many viewings during the holiday period, although to be fair this isn't probably a house you would expect a family to move into.
Probably the most sensible thing to do is to as the agent for feedback, why it is you are not getting views and what you need to do to sell it in your desired timescale. It's part of their job to provide that feedback.
Don't waste your time painting the toilet blue, installing the most enormous wall clock you can find or karate chopping the cushions. Despite what some people believe, this is not going to add 20 grand to the value of your house.
