Overall, a decent stay with great views of the Grand Place. I think the selling point for this apartment is the windows overlooking the Grand Place. I enjoyed the background noises of people dining and chatting outside. The host team also made a cute little pamphlet with instructions and travel tips they send before you check in, which is helpful.
The pros: The location! The apartment (separated by a hallway between living/sleeping space and bathroom/kitchen) is renovated, clean, and very stylish. It has an air conditioning unit. And the host team is quick to respond to messages.
The cons (some of these were just situational for us): The AC didn't work the whole week we were there. We notified the host team of this (and a few lights that fell out of its ceiling socket), which the host team immediately responded saying they would fix the issue. However, a quick response did not lead to a quick follow up, and I had to keep reminding them about the issue until they told me they would send maintenence over half way through our week's stay. I asked if they would notify me when maintenance would come, but only at the end of our stay got a notification that maintenance reported there was a missing piece in the AC. This means that not only did we not have AC all week, but that maintenance came into our apartment without our knowledge. These were my biggest issues with my stay, but hopefully this will not be an issue for others since the AC can be fixed. And if there are no problems, then the communication/follow-up issues won't exist either.
The only other thing I would say is that this apartment looks visually striking (modern and chic) but isn't really as comfortable for a longer stay. There are several flights of stairs to get to this apartment (which can get tiring after walking around all day, and is very difficult for travelers with lots of luggage). The sofa bed has a painting on the wall right where your head would go if you were to sit up in bed (to watch TV, etc), so you can't really lean back and relax. There's no trash can in the living area, so you have to walk through the hall to throw away trash in the kitchen/bathroom. The bathroom shower is really nice, but there's no where to put clothes or space for toiletries or your phone or whatever. These are minor things that some people can overlook, but it made for a suboptimal experience for us.
