We stayed in this apartment for about four months, as a family of two adults and one child. Overall, everything was good.
One of the main reasons why you might want to stay here is the apartment's huge private terrace.
The location is good, as it is not far from the city center (a 15-minute walk) and close to the beautiful Jardim da Estrela garden (a 7-minute walk).
It's a quiet place that's conveniently located near a good supermarket.
However, please keep in mind that the apartment is not new or recently renovated, and it has some issues. For us, these problems were not critical.
