Marcelo's flat is at a great location in the city. It's a short walk from St. Michael and St. Gudula Cathedral. It's also within a few minutes walk to Brussels Centraal station and Grand Place. The flat is comfortable and quite. It has most of the amenities one would need on the go. There are a couple things which I wish could be better. First, the bathroom is a bit small but I do appreciate that it's a private bath nevertheless. Second, the heater weren't able to keep up with the extreme cold when we were there. It kept the place not cold, but not warm either.
Marcelo was very welcoming. He greeted us when we arrived and gave us an introduction to his flat and nearby attractions. He was very nice to leave us a loaf of bread for breakfast. I would recommend his place to anyone who wants to spend a few nights in Brussels.
