I spent 2011 in the US working on my PhD in a town near Boston. This was my room. I know it looks very collegey:-) but I really liked it actually. I think the budget for decorating this room was lets say 80 USD (not including the cost for the bed which was somewhere around 200 USD) .
First night. Its not bad but it looked empty and impersonal. I bought the bed and borrowed everything else from friends.
So I used my clothing, posters and some things I found as a decoration.
And this was my room for the last 3 months when I moved into smaller room in the same apartment.
Carpe Diem, M.
