Overall, we had a lovely stay at José's apartment. The location is excellent. It's an easy walk to 2 metro lines, making travel throughout the city very easy. The neighborhood is safe and clean. There are several grocery stores within walking distance and a laundromat a couple of doors down. This two story unit has tall ceilings and large windows which allow in a lot of natural light during the day. The beds were very comfortable and the bathroom was a good size for 4 people. José provided several thoughtful touches, like shopping bags, plenty of bathroom necessities, umbrellas and live plants -- which is a touch we rarely see in Airbnbs.
José as a host was impeccably polite and accommodating. While we did have a couple of issues during our month long stay with wifi and the hot water heater, José was quick to address the issues and provide timely solutions. (For those who work remotely and for whom this type of information is important, by the time the wifi was repaired the download speed was approx. 35 Mbps and the upload 15 Mbps)
The only issues I would bring to the attention of other travelers are 1) the walls are thin and the neighbors are loud, especially on the weekends. And 2) the stairs inside the apartment are rather narrow and steep -- not easy to go up and down. On the plus side there are stairs in the hallway that allow you to bring bigger items up and down.
All in all it was a wonderful stay and I'd recommend it to anyone visiting Brussels.
