The appartment is lovely (bright, super clean, nice interior) and Mariana was so welcoming. The communication and checkin was outstanding and she also gave us some tips for restaurants and activities in Lisbon.
The location of the appartment is very central so you can walk to most of the spots in the city center (~20 min.)
There are nice restaurants nearby btw. like a portuguese tapas restaurant Petiscaria de Ideal or a Fado restaurant Sr. Vinho.
Also you can to a good supermarket by food.
Really recommend Marianas appartment!
