My stay at Mariana and Rita's place was really amazing - the little apartment is in fabulous location, you can pretty much walk anywhere, as a solo traveler I never had a bad experience walking alone - day or night, everything you need is close by...It's a quiet area, even more so if you close the windows. The place is nicely renovated and thought out and Rita is a good host, too, very easy to communicate with. Make sure you go to Travessa di Terreiro a Santa Catarina number 3 - the other 3 in the address is the 3rd floor. Excellent stay and would definitely go back again.
