Manuela is a lovely and accommodating hostess, and the apartment is very livable. In some ways it is better than the pictures - the furniture is traditional, but the apartment itself is very modern and fresh. We appreciated the roomy shower, and the welcoming treats and extensive folder of tips and recommendations Manuela has put together.
It is on a major street, a block away from the pedestrian walking street and the train station, but the double windows kept all noise out. We had no problem getting to all the Porto sights, either walking or taking the nearby trams and funiculars. Lots of restaurants nearby; groceries and necessities as well.
Highly recommended for a Lisbon stay.
