The location of the apartment is perfect, near the metro and train stations, very central, with bars and restaurants nearby. As other reviewers mentioned it can get a little noisy due to its central location.
The apartment is as shown in the pictures. It was a little small for 4 people but we had a great time.
Communication with Mario was easy and we were able to check in late at night, which was very nice.
We would recommend the Oportoflowers to anyone looking for a central location in Porto!
