We slept in the loft for a week and generally had a great time. Ana & João are lovely hosts and quick to respond. You do share the building with several Airbnb'ers, but you have little or no problem with this, even though everyone walks into the building next to the loft. Personally, we found the street noise quite intense and couldn't open the windows because of that, making it damp too, to the credit of taking a shower (no window). The location of the loft is really great and nice just outside the center, so you can escape tourism and discover the 'real' Porto. The train to Braga (recommended) is a 10-minute walk from the station. Furthermore, many nice and cozy eateries nearby.
