I had a lovely stay at Marilia's appartment. It was spotless when I arrived, the kitchen had all the equipment we needed, and the beds were super comfy! The location is also second to none. Most of the main attractions are only a few minutes walk away, and it's also near lots of great restaurants and cafes. The nearby corner shop is good for basics, but if you want to do more cooking then it's worth making the 10-minute walk to the supermarket. I'd definitely recommend this appartment to anyone visiting Porto.
