I stayed and worked in appartment for almost three weeks.
Great appartment. It's located on fifth flour (last one) and it has access to the roof. Amazing view from the roof.
Pros:
* Perfect location. Next to cathedral, Tagus river, "Arco da Rua Augusta", etc. It's right in the center of everything.
* Access to the roof
* Good water pressure both in kitchen and bathroom
* Has air conditioner
* Nice expandable table
* You can open windows
Cons:
* Noisy area. There is a barking dog (very loud at night), and you can hear people from the restaurant until 1-3 AM.
* The refrigerator makes a lot of noise at day and night.
I had to sleep with earplugs, othervise I could not sleep.
