Despite on my booking request for a quiet room, especially no low frequency noise, first I got a room with a very loud outside part of the Aircon. I asked to change, they called the floor staff, and she knew exactly which rooms are not noisy and she confirmed the problem in my first room. I'd be happy if they were more considerate from the beginning.
The staff is very nice and helpful though.
The curtains are not blackout.
The bed is comfortable even for a person with back issues.
Clean.
I needed this particular location close to the port, but San Nicolas, which is in a walking distance, is nicer and a bit less touristy. Porto Madeira barrio is still not noisy at all during the night, at least you can't hear anything from the hotel room. Just the streets are much more crowded and less clean than in San Nicolas.
Good security at the lobby. The elevators which close the inner door automatically.
Generally, take your own shower cup etc with you when travelling in Argentina and Brazil.
