I haven't stayed at that hotel, its located downtown near the presidential palace, Casa Rosada. 'gaslight district' seems to be a stretch, I doubt there have been any gaslights down there in 50 years! Although that's a cool neighborhood to visit for half-a-day I'd never stay in a hotel there. As mentioned throughout this thread, Recoletta & Palermo are much more interesting places to stay. There are numerous hotels recommended in this thread, it will take an hour or two, but its worth reading the whole thing before you head to Bs. As.
