We had a wonderful 10 nights stay at the apartment. It was well-equipped with everything you'll need for a comfortable stay and it was very clean. Everything was very well laid out in the apartment and very functional. The best part was the balcony view to the Douro River. It's on a charming street quite popular with tour groups during the day. Claudia was very responsive to any questions or needs we have, and she checked in on us during our stay to make sure we have what we needed. She also booked us a car to pick us up at the airport as well as drop us off on our return home. Even though you can easily take a train, we think it was well worth the cost for the convenience especially when it was raining or after a long flight. The driver Alcino was very nice and professional.
The location was great and easy to walk to every place you can imagine within Porto city center. We even enjoyed a walk all the way to Foz where the ocean meets the river. Sao Bento train station was an easy 5-7 minutes walk. There is a secure ATM at Banco Credito Agricola only 2 minutes walk away located across the street from the Starbucks.
I have to mention that there is some construction going on in the neighborhood during our stay, so it can be quite noisy during the weekdays if you have the windows or balcony doors open for fresh air. However, you don't hear much noise if you keep the balcony doors and windows closed. Overall, we really enjoyed our stay and will recommend the place to our friends.
