A very nice apartment in cosy Bairro Alto, where you will find lots of restaurants and bars.
You are in walking distans to all of central Lisbon, and you have two miradouros close bye. There is also a metro station near.
Since the area is very intense during evenings and nights, you must be prepared for a lot of sounds from the street and from nearby bars.
I stayed there for a month, partly working and partly on vacation and I really enjoyed my stay!
