The apartment is great and easily accessible, we walked to it from the train station São Bento without any problems. It is not in the immediate centre of Porto, but sufficiently centric to have a good access to all the hot spots of the city. Just on the border of Cedofeita, besides the Baixa, you have immediately some very nice cafés and restaurants around.
We loved the modern style of the flat, a very nice contrast to the old architecture of Porto in the area. It is absolutely as one would expect it, it looks exactly as in the pictures.
The communication with Mixo was very easy and we received the check-in information pro actively, but also the replies to messages in a very short time.
For us it was great to stay at the apartment and it made our stay in Porto very memorable. I would absolutely recommend the place to others.
