Isabelle's home is perfect. The rooms actually are much larger than they appear in the photos. And the house is very quiet despite being in the center of the city. The stairs are steep, but no worse than in many homes in Europe. The bathrooms (2 full and 1 half) are new.
A word of caution -- be sure to follow Isabelle's directions to the parking garage. Ghent has been largely closed to car traffic, and you will receive a ticket if you drive in the wrong area.
We would love to stay at Isabelle's home in future and spend more time in Ghent!
