The area where the house is located is really good, close to public transport, shops, bars...
I've been there for a month and I felt really confortable. I could feel like at home. (Just a bit colder than my one in Spain) ;)
The welcome pack was really helpful, and all books that there are in the shelve are really interesting if it is your first time in the city.
Even if I didn't expend lot of time with them, I could say that they are a nice family, pleasant, reliable and really kind. And their kids are so cute. Specially, I remember Siam looking at my toast every morning as if it would be for her!
I highly recommend this place to stay either in holidays or if you come to work to BXL.
