This place is beautiful and stylish. Very comfortable with all necessities provided. Centrally located and in an old renovated building that adds to the charm of experiencing Porto.
Note that the check in is not at the location but instead you are able to choose from three locations around Porto to pick up your keys. Our location was a bar at a central area, and our keys were in a basket in an envelope with our name on it. While is effective, from our perspective it lacks the personal touch of meeting a host and interact with them. But if this is not your priority, then you will be fine with the system they have in place.
The other thing you must consider is that as it is an old building, you can easily hear your neighbors up walking around.
Overall we were happy with the place and if we come back will certainly contact Duarte again.
