My girlfriend and I stayed in Maria's apartment over New Years Eve 2015. Maria Luiza is extremely nice and went out of her way to provide helpful tips. The unit is functional and is in a perfect location one very short block from Copacabana beach (though construction of a new museum blocks most of the pictured beach view).

However, the unit has a few issues. First, the air conditioner is all but completely broken and does little to cool the room. As a result, you will end up feeling sweaty after spending a short time in the room at any hour of the day. Second, the unit and the bed were sandy when we arrived. Third, the electrical system is very old and requires turning off the air conditioner every time you turn on the electrically heated shower.
