Trust them. Woman alone in Buenos Aires, I was nervous about not hearing from them until right before my visit. The information on Hotels told me so but still, I’m a planner so I worried. However, Babel Belgrano was true to their word and fulfilled, I mean, exceeded my expectations. Ease of check in( I arrived at 2200), cleanliness and comfort made this a welcomed treat. Yes, there is construction all around the neighborhood but not until after 8 am(remember the time difference). Stores and shops nearby.
