Help to find a cheap place in Tokyo

Hey, as a part of my education I'm taking a three month stay in Japan to do some empirical research. My University unfortunately cannot be to any assistance regarding finding a place to live during my stay. Therefore I'm asking if you have any suggestion or can recommend something. I'm a student so I don't need some fancy apartment. Just as cheap as possible

I have searched the Net and found many sites that offer different types of housing. But it would be nice if you had some personal experience about finding a place to stay in Tokyo. It's a lot of money so it would be nice to know that I'm spending them right.
I'm also thinking about sharing an apartment with some other person/student as a possibility. But again that is not easy to arrange when you don't know any people in Japan.

But please write any suggestions you think could be useful for my little project.

Hiraokaﾂ Guesthouse
It is one minute on foot from Ueno station.
A rent is 39,000 yen for one month.
I think that here is the most convenient.

Thank very much for the reply. Do you have personal experience with some of the links or do you someone who has?

I am sorry,
I had not used them.
I lived in Kanto for 16 years,
I think that I can advise you about Tokyo.
What university do you go to?

I had a good experience with Sakura House. Their guest houses are nice, everyone gets their own bedroom with a common kitchen/living area, and not as expensive as your own apartment. You're best off having them show you places so you can make an informed decision about the place. I got a place without looking at it, and it turned out to be too close to a train station (I had to wear earplugs to sleep). But they have a lot of places all over the city, so you can easily find something convenient to where you want to be that works for you.

Thugh this isn't a part of your question, if you need a cheap travelling company go to www.japanspecialisten.dk where you can find cheap companies, cheap places to go (you're not gonna study all the time ) and etc. for us Danes.
