We had a realy nice stay in Porto and in this lovely Apartment.
You need around five Minutes to reach the Metro and from there, you need additional 20 Minutes to the old city center.
A shopping center is right next to the building and can be reached easily. When you look outside the window, you can see the stadium which could be nice for soccer fans.
Unfortunately we had some minor communication issues with the doorman (they can only speak portugese) but nothing that can not be solved with a translator app.
The place was clean and things for daily use were present. if we missed something, we could easily buy it in the shopping center.
The washing mashines and dryer were very useful (still need to buy detergent) if you plan not to bring much clothes with you.
On the whole it was a very cozy and nice apartment but in need of some minor repairs (no deal breaker but disturb the positive overall picture).
