We stayed in Room R at The Dutra and our stay was as expected with no major issues. Just a couple things to mention as a heads-up:
1) As others have mentioned, there is a significant amount of street noise during the evenings/nighttime. It didn't bother us too much since we were very tired after exploring the city and slept through it all, but just something to be aware of if you're a light sleeper!
2) There is no ventilation system in the bathroom (just a small window). The stale bathroom air can get to you sometimes, especially since the bed is right next to the bathroom.
Overall, we had a great time and the location of the inn was prime! Super close to lots of restaurants in Little Italy and the harbor! :)
