Gundega and Antonio met us at the apartment (we arrived early, around 12noon) and enthusiastically explained the best places to go in Porto. They explained the neighborhood, local cafes and restaurants, supermarkets, walks. They love Porto, and gave us enough of a taste for us to love it too. During our stay they answered questions quickly.
The apartment is exactly as described - a studio flat with a large terrace. It has the sun in the evening, and there are no windows overlooking - in fact you can see a lot of Porto from the terrace or window.
The neighborhood is pleasant; more importantly, it's easy (and safe) walking to the sights and tastes of Porto and if you prefer to take the metro, there are two stations really close, both on the direct line to the airport.
We traveled to see nearby cities - access to inter-regional stations is also great
