Helana, Pedro, are wonderfull hosts. Fast and clear in communication and providing any information you need. They also arranged airport transfers for our group of 8 which was convenient.
The house is located conveniently close to all public transport as described. However we also walked to the center of town in20-30minutes. Alternatively taxi's and Ubers are cheap (4euro to the center)
As the house is located just outside touristic area it gives a feeling of living in between the locals and seeing a bit of the real local life in Porto.
The studio's are looking fresh and refurbished. Nice to be with the family together but still have the privacy of the seperate studio's and bathrooms.
One critical note is that the sofa beds in studio 2-3 are not very comfortable.
Overall I would recommend to stay here in particular in Studio 1 as it has the nicest atmosphere and ammenities (spacious bathroom and kitchen)
