The apartment is very good situated. Not far from the Metro Casa da Musica ( 12 minutes walk ) and to the old town 10/15 minutes. A big Shopping Mall also nearby (6/7 minutes ) with also the food market. You can sit, drink and eat small portions of all kind off kitchens.
We only spoke to Martha by Mail, the person who checked us in was very friendly.
It was a pity that there is very much traffic making it not so fun to sit on the balcony or to have the Windows open.
