Marie's house is absolutely wonderful. We had two families of four and were very comfortable and happy. The renovations to a very old house maintain the beauty and charm while providing entirely modern conveniences. We especially loved the bedroom and skylight on the top floor, as well as the showers. The stairs are indeed quite steep and small, but you get used to it fairly quickly. It's a quick walk to beautiful parts of the Ghent, which we found to be our favorite stop of our trip in Belgium. The house is beautiful (especially the statue outside) and there is a small market just a short walk away. Marie is a wonderful host--warm, provides helpful information, and responds very quickly.
We highly recommend staying here. (We also recommend the Golden Gai restaurant (ramen), but judging by the smells while walking around there are clearly many good options.)
