We had the chance to stay for 4 nights at Graça's place and it was all perfect! Everything met the description, the room was so clean with a large space and a lovely garden on the backyard. The house is about 10 min walking from the Casa de musica metro station, but there are many bus stops around the house. A market and a pastry are very close to the house.
Graça and her family, just as the majority of Porto's people, are very friendly, very helping ... and speak at least French and English! Graça reserved a taxi for us to get to the airport and she even woke up at 5:30 o’clock to make sure that everything was okay.
If we'd have another chance to visit Porto, it would be at Graça's where we'd love to stay.
