Location is perfect. 1 min walk to baixa underground, 5 mins walk to placa de commercio.
The flat as you can see from the picture is really nice, but few things might be better (e.i. wiring is poor in the rooms)
Due to the fact that the apartment is situated in the back of a shopping centre, during the night is pretty loud.
If you usually lives in a quiet place, this might be annoying.
Communication with the host is perfect, as well as for the check in.
