Very good tip how to save money for your stay in Prague - the advice is very simple: Sleep in a hostel instead of a hotel. The price for accommodation in hotels is far more expensive than in hostels and if you plan to be there just at night time, it is just a room with bed that you really need.
If you prefer to have your own bathroom there are a lot of hostels which offer rooms with private bathrooms and toilets.
Also, to save even more, look for accommodation not directly in the city centre.
