If you want to stay at old European neighbourhood with pastel coloured apartment buildings which you see in a postcards, this place is exactly what you are looking for.
Lots of cafes and restaurants which is full of local people even though this place is just a few minutes away from downtown metro and tourism bus stop.
If you are not confident with your health (bad knee, short breath, etc) I won’t recommend you this place since this place is on top of 45 degrees hill which is typical Portugal neighbourhood.
