The apartment is exactly as shown in the pictures and Luis is a very welcoming host. He showed us around and gave us loads of tourist information on Porto. The apartment is bright and sunny and in the perfect position to explore the city. Around the corner is Sao Bento train station, metro and buses. It is an easy walk to the Cathedral and the walkway on top of the bridge.
The large bed is super comfortable. I did find the room warm and a bit stuffy of a night. There is a fan but I think I would struggle in the summer heat without air conditioning. All in all it was a great stay.
