Isa was super friendly and helpful. You just can ask her any questions. We had a good stay in Porto. The appartment was super clean and its Style is old but beautiful. The Place of the appartment is perfect because you are Not directly in the middle of the city so Noise is Not a Problem, but you are close to the center to visit everything by feed. Just the bed was a little bit small, so nothing for tall people. We would recommend this place for your stay in Porto! :)
