Lovely, clean and newly renovated apartment with elevators. We met Nuno by the apartment. He got us a map and went over the city and attractions and gave us some good tips. Nuno was very helpful and responded to our messages quickly. The apartment was about 4min walk to a large grocery store (very handy especially since we were travelling with little kids) and right beside many cafes and subway entrance. From the apartment, there is about a 20min walk downhill to the historical riverside (we were walking down with a stroller and our 6-year-old son). We also walked back uphill to the apartment from the river (again with the stroller) and it took about 30min and was quite doable ( if you are fit for walking!). Don't bother with renting a car as there is no space to park the car anywhere. Use Uber if you need to go around with a car as it is quite affordable (we paid about 9 Euro from the apartment to the "Sealife aquarium" by the beach (on the far west side of the city).
All in all a perfectly clean apartment in a perfect location :)
