The location of the apartment is perfect for visiting Belem district.
It is next to the public transport so it is easy to reach the city center into 30 min.
The apartment is clean and very convenient is you spend most of the day visiting the city.
I will recommend this apartment if you come to visit the area for 2 or 3 days.
2 slight notes of caution:
-The apartment is a bit noisy
-The dining room is very small so it might not be convenient if you want to eat at home with a couple of friends
