The apartment was beautiful, super clean and well equipped. They give you a free Porto bottle of wine with your stay, and fresh bread and croissant in the morning.
The communication was good with Eugenia and Luis. The apartment is almost in the middle of old Porto, you can easily walk to restaurant and historic point of interest. I would definitely stay here if I visit Porto again.
The extra nice touch is that Eugenia took the time to explain the history of Porto, the sites to visit, the restaurants (the expensive ones and the ones if you want an authentic Porto-Portuguese experience.
Just book it, NOW!
