The host/co-host offered assistance well before our arrival. The apartment was actually better than what was in photos. Kitchen was better equipped than even at my home. The apartment was in the center of the downtown, walkable to everywhere (except to Belem, unless you want to break your legs). The only downside is the dark staircase leading up to the apartment: it is supposed to have lighting but actually the light of part of the floors was not working, so we had to walk in the dark. Overall a great experience to stay in Baixa, and I will recommend to everyone.
