Me and my mom stayed at Justine's and her boyfriend's place for 3 nights. Justine was answering messages very fast and asked for details when she needed. We arrived at 19:30 but the arrival time was flexible. The house is very easy to find on Google maps, 3-floors house / apartment has a separate entrance, you just ring the door bell
The apartment is very bright and clean. The kitchen and living room is on the first floor, 2 guest bedrooms and bathroom on the second and master bedroom on the third. There is a small outside area, ground floor balcony. Mind that you'll have to walk stairs quite a lot. There are a lot of books and plants everywhere
The bedroom is small but very bright and cozy, with high ceiling , double bed, chair, some hangers, books, big window and blackout curtains. Room has big radiator but we didn't use it. You can lock your room with a key if you want. Bathroom is big, no problems with warm water in the shower. Kitchen is very modern: with induction cooker, microwave, teapot, filter coffee machine, dishwasher, oven. You can have some tea (no black, just green and herbal), coffee, spices for cooking. The only problem for me was that everything was quite high and I'm pretty short :)
Walk to Sint-Pieters station is ~25 min, bus is expensive - 3 euros. Closest supermarket is AH Overpoortstraat - 10 min walk. Make sure you understand how to open the front door, it has a tiny trick :)
Hosts are very welcoming, with great English. Ghent is amazing - so cozy and vibrant. We loved the city and our vacation despite the weather swings
