I stayed for a week at Joost's apartment for a conference and to see the Christmas markets. The apartment is beautiful, modern and clean with all the amenities you might need. It's 10 minute walk to the old town and maybe 25 minutes to Gent-St-Pieters station (there are buses and trams if you don't want to walk). Check-in was easy and Joost was happy for us to leave out luggage at the apartment until our flight on the last day. Would definitely stay here again.
