Porto Bay Rio Internacional Hotel

One of Copacabana's top beachfront hotels, Porto Bay has 117 stylish rooms—many with private verandas, all reasonably-priced and luxurious. Though small, the hotel's rooftop pool offers guests fluffy white chaise lounges with enormous beach towels and even more massive ocean views. At night the rooftop lounge becomes a trendy hangout for revelers looking for top-notch capirinhas and bosso nova music. And everything from the bars (both of them), to the saunas (again, both) to the on-site babysitting service has been curated with guests' relaxation and delight in mind.
