One of the best places I've stayed. Great location and you have a fantastic view of the city and Douro river. The city and most restaurants, shops and tourist attractions are easily accessible by walking. The metro, train and bus stations are close by as well.
Jose met us upon arrival and took the time to give a thorough overview of the area (a bottle of port wine and a box of pasteis de natas were a welcome treat!). His recommendations for restaurants, bakeries, and interesting things to do and see while in Porto were spot on. He is genuinely nice person and very helpful.
The apartment is very clean, comfortable and in a safe location. Honestly, we had everything we needed. If you plan on going to Porto, I highly recommend staying here, you won't be disappointed.
