Great experience!! I love Porto and used to lived there. This location I believed it's the best one - very central and extremely close to the Trindade, the central subway station from where you can get to and from to anywhere.
The apartment it's cozy, clean, well decorated and have everything I needed. All the other guests respected the rules. The whole check in and check out process is well organised and runs smoothly.
But the highlight was the host: Antonio was caring, available and willing to help me.
From someone who knows and love Porto: It's a really good option!
