This home is located in a picturesque building (so much so that while you're staying in the apartment, many fellow tourists will be photographing it from the nearby square) and the architecture itself is fascinating. Everything you need is nearby. It's perfect for a pair of traveling friends, as there are two large beds available along with a futon couch. Appliances are modern and the space has plenty of light and interesting features.
Since this apartment is in a bustling neighborhood, there is quite a bit of traffic and street noise (and some bars below the windows) - so it's worth keeping that in mind if you are looking for a very quiet location. The wooden floors also creak a lot and so you'll hear the upstairs neighbors and also make some noise when you walk around in the space.
When my friend and I stayed there, it was an exceptionally warm weekend and we had to sleep with open windows, so I needed to use ear plugs because it was too loud late at night. This is not at all Florence's fault, though, and so the apartment rating isn't affected.
I definitely would return to this very well-priced, beautiful apartment if I find myself back in Brussels!
