Good location, nice apartment overall.
The living room is quite spacious and nicely decorated but the sofas are not that comfortable.
One of the bedrooms is very small with very little space for your stuff, so if you have big luggage they won't fit in the room.
There are restaurants right under the apartment which is great for a coffee in the morning.
The park in front of the apartment is very nice.
Silvia was not there to welcome us nor did she give us some tips/information about Porto as hosts usually do. We only met her in the entrance when we were leaving. However, she responded directly when we asked her to call a cab for the airport.
