We stayed for 2 nights in mid-April in the larger of the two rooms. Loved the walk-through shower (you can open the blinds on the nearby window and have a great view of the neighborhood!).
I can’t really offer any more to say that hasn’t been already captured in the write-up by the previous reviewer (malabarfly). I completely agree with everything he writes about Compagnons11.
If and/or when I return to Mons I would love to stay at Compagnons11 again! Fantastic place and fantastic hosts!
