Location is fantastic - we were able to walk to most places and getting a taxi is easy. Value is great too.
The flat is quite tight, especially the bathrooms are tiny, so just be aware that this is a city apt you are choosing for the location and not as a place to necessarily pass time.
Because it's on a main street in Baixa, I thought it was loud at night but the rest of my family didn't notice so maybe it was just me/my room.
Also beware its a 3rd floor walk up!
