The apartment of Goncalo & Miku was very nice. The place was clean an it lies in a quiet street, yet not far from the city center. (10min with public transport / 20min by foot)
You can find a lot of bars and restaurants in the surroundings, as well as some nice shops.
The communication with Goncalo&Miku was easy and they and their team made sure to always be available for any question that may occurred.
The only small issue is that the ceiling is very thin so you can hear every footstep of the upstairs neighbours, which seems to be a holiday rental as well.
Nevertheless, we can totally recommend the place for people staying for a city trip over the week or weekend!
