Cute apartment, great view and location, with some caveats.
First, the positives:
1. Location is excellent. Short walk to Grand Place and tons of dining options. Coffee shop downstairs, and great breakfast option very close by. Also a small market (Spar) close by.
2. Plenty of space for 4 adults to stretch out and relax. The couch was comfy, and by pulling a couple chairs over, we were able to sit around the living area after the day and wind down.
3. Two full baths is great for 4 adults. For each couple to have their own bathroom is key.
4. View of Notre-Dame du Sablon is amazing.
5. Good wifi.
6. Nicely equipped kitchenette. Dishes, fridge, Nespresso maker, small cook top if you want to cook.
And the not so good:
1. Noise is extreme. If you want quiet, this isn't the place for you. Traffic all day and night. Rail line and buses throughout the day. Sirens all the time.
2. Shower in the second bathroom has terrible water pressure and constantly goes between cold and scalding hot. We ended up using the shower in the front bedroom. So between the 2 showers and 1 tub, only 1 shower worked well.
3. Tub drain in front bedroom does not seal, so you can't use the bath.
4. No self check-in procedure. Had to meet the host, who was 15 minutes late from our agreed upon time. Restaurant workers downstairs knew where the key was, and showed us, so we didn't have to wait for the host to meet us.
Overall, we were mostly happy with the apartment. It has it's pluses, however I suspect there are better values available.
