Had a great stay at the Dutra while at a work conference at the convention center. For a way better price than nearby hotels, I had a serene patio, kitchen, tons of storage space, very comfortable bed, and great all-around vibe. The Dutra is centrally located and I walked almost everywhere during my stay (about 25 minutes to convention center along the water)
As others have noted, the restaurants across the street are slightly noisy at night, but nothing that kept me awake. I did not use the white noise generator or ear plugs they provide and was fine. However, playing it safe, I might avoid this spot if you’re a particularly light sleeper and plan to stay on a weekend.
