I chose Pereira’s place because of the location. It is located in an old Gaia area and I enjoyed nice walk alongside the Douro River admiring a beautiful view of Porto downtown.
The apartment is compact and good for a solo tourist like me, and well equipped (a washer with a detergent was very useful).
As the apartment is on a very narrow one way street, if you want to call Uber, it is safe to meet your driver on the riverside road (go down to the left from the apartment to reach at the Riverside).
Pereira was very responsive and helpful to make my trip easy. Thank you!
