This is where I stayed in Kiev in January: arendakiev.com/en/apartment_1/819.html
I have used them several times. You can google for similar companies in Kharkov. Their prices should be a little lower than Kiev. If not I would suggest searching some more.

Hi,
This apartment is good, but it not very economic. Anton - what is your budget for night and are you looking apartment in the centre or it may be on the sleeping area?
I know one place next to Akadem Mistechko subway station, room there costs app. $35-45
