Susana´s place is very nice. It is a small apartment, well located and even being on a busy street, at night it was not noisy.
Susana was very helpful in every way. She is a great host.
Be aware, that there are no closets to put your clothes away. Only a rack with some hangers.
We came by car, and were lucky to be able to park on site, however the ramp to park was difficult, so we did not use the car at all. My suggestion is not to go to Porto by car.
Everything is close by and easy to walk.
