Filipe was really nice and welcomed me very well.
The apartment is functional and well situated, next to Sao Sebastiao metro station and to parque Eduardo VII. In the neighborhood, you can find small shops to buy food and drinks. The walk to Bairro Alto and Alfama is worth doing if you like walking.
Beware though that this part of the city is flown over by approaching airplanes landing at the airport, which can be a little noisy.
