We spent three days and two nights in Marcelo's apartment.
The apartment is located next to the Saints Michel and Gudule Cathedral, so we were able to stroll around without taking any bus or metro. It was very quiet, well furnished and organised, ideal for a couple which wants to spend there a few days.
Marcelo was a nice host: he gave us a city map and some useful tips about nice sightseeings and breweries, and he also provided us something for breakfast.
We definitely recommend his place!
