At Marielí's place you get really good value for your money. Even on the weekend it was not too loud so I could sleep with the window open. The connection to the center is quick and in close walking distance. A great plus is the separate bathroom you get! It's equipped with shower gels and shampoos so if you travel lightly you don't need to buy anything.
I especially liked that the room is for single travelers as usually you have to pay a premium for single occupation.
