This place is an outstanding location.
We rented a car and were able to pay to park at a nearby 24 hr parking that was about 5-10 min from the apartment. We had no problems walking with the bags to the apartment for the 2-3 blocks distance.
Very safe area and prime location with a pharmacy 3-5 min away where we got the rapid COVID test for our return to the US. Area with plenty of restaurants and centrally located to all the main attractions the city has to offer. Check-in was a breeze, the apartment has an elevator, was sparkling clean and there was even a mini bar with goodies for you to consume and leave the cash for the items consumed.
Finally, the communication and recommendations from the Host couldn't have been better. I highly recommend this place if you will be in Porto with a group of 4-6 persons.
