Florence's apartment was amazing! It was clean, spacious and was in walking distance to central Brussels. My fiance and I only stayed three nights; it's unfortunate we couldn't stay longer.
Just a note: the apartment is across from a main gathering/park area and is above a bar, so there will be noise in the evening, but it was never too loud or disturbing, in my opinion. And the patio was a perfect place to people watch and listen to the musicians that played in the park every night.
Florence was an awesome host. She wasn't able to meet us in person, but was always quick to respond if I had a question or when I had to update her about our arrival. She even left us a sweet welcome note on the chalkboard when we arrived.
I definitely recommend staying here if you are going to visit Brussels!
