This place is a great option for a week long stay in Porto. The metro really is on the doorstep however we just walked every day as it is only 20 mins or so to Ribeira. So this is a good location if you don't mind being somewhere a bit quieter.
The apartment was very clean and had pretty much everything that you'd need. We would say a full length mirror would be handy though!
My aircon started leaking on our second day however the problem was fixed very quickly and we were given replacement towels as I had used mine to soak up the leaked water. The LovelyStay team are quick to reply to any messages and are overall really helpful.
We enjoyed our stay here.
