We had a great staying in Alexandra's place! The apartment is cozy, warm, perfectly clean and in the ideal position to visit Porto, with almost everything at walking distance. We'd also like to point out that, although its central position, the apartment is really quiet and we slept like babies.
We had some minor communication issues due to the fact that Alexandra is often abroad, but this didn't affect our staying at all...we would definitely recommend Alexandra's apartment to anyone!
