Our stay at Paula's place was very very convenient. The whole building looks fairly upper class and modern, in and outside. We were lucky in getting the apartment under the attic. The interior is very appealing and you have everything what you need. We felt very comfy staying there. Location-wise, the apartment is within a couple of minutes' reach of basically everything that your heart may desire such as the Torre dos Clérigos, Sao Bento train station and even the Douro River or Ponte Luiz I can be reached within 10 minutes walking. With all this being said, we can only higly recommend staying at Paula's apartment.
Muito Obrigado, Paula!
