I've been for work in Brussels and I've spent two nights at Mariano's apartment. It was very close to the meetings' venues so for me was perfect but It's ideally located for everyone because it's near the metro stop and close to supermakets and other shops. If you love to walk it's also possible to reach the city center in 15-20 minutes. It is at the second floor without elevator, for me was absolutely fine. The apartement is clean and well equipped, the bed is very good. Unfortunately I haven't had the opportunity to meet Mariano but we have been in contact by messages, he is very kind and attentive and he contacted me immediately after my arrival to be sure that everything was ok. His friend Ruben give me the keys, he is very nice and helpful. I reccommed this apartment and Mariano.
