This apartment was exactly as expected. The location was great (within a 10 minute walk to a metro, shopping on Avenue da Liberdade, great restaurants/bars), the apartment was clean and well-maintained, and Doris was a lovely host. She was highly communicative and responsive, and so sweet as to leave a welcome gift of food/bevie which was wonderful to be able to enjoy after a long journey flying to Portugal.
The only downside of this apartment (which comes with city living and is completely out of Doris' control) is the noise - with being in the heart of the city, the street can be noisy at night (especially on Fri/Sat) and since most of the bedrooms are street-side it was necessary to keep the windows closed at night to block out as much noise as possible. Also, smoking is so rampant in Europe that the cigarette smoke from the neighbors wafted into the apartment regularly.
Overall, I would highly recommend this place and a stay with Doris.
