Marilia's apartment was fantastic! So well located (and was so great for me because it was literally a 5min walk to the start of my Sandeman walking tour by Clerigos tower) and within walking distance to all the big attractions. However, because it's in a popular neighborhood and the flat faces the street, it was really hard for me to sleep at night because of the noise (and I was there at the start of the week).
It was also a little warm in the apartment with no AC but it wasn't a huge detractor.
It was also very clean, cozy, and perfect for one person.
Marilia was also such a fantastic host. My flight got in three hours before check-in and she was so accommodating and let me come by early. The cleaning lady was finishing up so I went for a quick stroll until the apartment was ready shortly after. Marilia was also so responsive throughout my stay.
