Xenia is very nice and communicative, she response fast too! we kind of lost our way from airport to her place but she is so worried and check on us every few minutes to make sure we were not lost!
Her house is so gorgeous, it feels like home for me and my friend that we joke that we will just stay and enjoying her house instead of exploring Brussels :D
Location wise is not too near to city centre, actually if there is no construction going on, we can easily take the bus no. 14 to Brussel North train station, it is only one stop away to Brussel Central train station where the city centre located at.
But overall, I recommend Xenia's place! Thank you Xenia for your hospitality :)
