Nice place in a newly renovated building with off-street parking. We enjoyed our stay here. The beds were comfortable, and the internet was stable enough for video calls.
The apartment is located a little outside of the tourist areas which helps provide a more authentic view of Porto, but it is an easy enough walk to the main areas or a cheap Uber ride away.
The apartment is located above a busy road, so there is quite a bit of street noise if you leave the windows open. It wasn't too bothersome though (we didn't hear anyone honking horns)
We would stay again.
