I asked one of the Ukrainian mafia, apparently Kiev is nice this time of year, local beers are pretty cheap. She has a house but she rents it out ascend isn't interested in renting it out to any football fans for one weekend.
If you are looking for a house for rent in Kiev (Kyiv is the right name))) just use booking_com there are some holiday houses there. It is good joice if you want to live as a group of fans in one place.
And also I posted a link above - facebook group with free couch for fans)
