Edu and Silvia were amazing hosts. They are very responsive, assisting problems quickly and really trying to help with everything you need!
The apartment is comfortable, cozy and spacious. look exactly as the pictures.
It was equipped and the WIFI was really good (we worked from the apartment few days).
The location is quite good, not exactly in the center - but pretty close. Just next to Trinidad metro station. There is a bus parking place just beneath the apartment, during the day if the window is opened - it can be a bit noisy from there.

The only thing you need to consider is that there isnt air conditinar in the apartment. During the hot days in the summer, it can really help.
During our staying there were 2 extremely hot days, Edu took care and gave us a fan. It was a life saver!
We really recommend on this apartment! It made our staying in Porto great!
