The location is very quiet, yet walkable to just about any place you would want to go. There is an absolutely beautiful park out the front door to the left and about a 5-minute walk. Stunning views of Porto and lots of places to walk or relax, peacocks and roosters everywhere. Maria was also very helpful in recommending restaurants, etc.
This apartment is very suitable for two friends traveling together because we each had a nice room with great windows to a peaceful courtyard below and each room had a big desk next to the window.
I would recommend this apartment and Maria.
