I honestly dont' find her attractive at all. I can see that she is quite an attractive girl generally though, nice smile etc, but i really can't see past her personality and behaviour, and for me that makes her one of the ugliest housemates, if not THE ugliest.
Judging purely on external beauty, Saskia is the most attractive girl in the house, by far. And she seems like a decent girl inside, although i'm still waiting to find out if her views of foreigners in her audition was purely to get in, or what she actually believes. I won't make a proper decision on her until i find that out.
