My partner and I stayed at Bie and Ton's place with some friends from France during Antwerp Pride.
It was a great experience.
The communication upfront was swift and responsive, they were very welcoming on arrival and the appartement was all we wished for (clean, plenty of room, cosy decorated).
We didn't have much contact with Bie and Ton during our stay because everything was all-right!
If you hesitate, don't, I'm sure you'll have a great time too.
We'll be back in the future for sure :-)
