Kristof's place is very well-located in Gent. It's close to everything and right above his breakfast restaurant open on weekdays.
One should be aware that this apartment is on the fourth floor with only stairs to reach it. Since this is Europe, they don't count the ground floor, so think fifth floor if you're from America. I wouldn't recommend it if you're disabled or have difficulty using stairs.
However, we had a great stay. The area was very nice and the tram stops were close. It was so easy to get anywhere by walking.
