We had a wonderful stay at Ana's apartment. It is very well located for young travellers who want to discover the city by foot. The apartment itself is bright, with big living spaces, a kitchen that gives you a lot of independence, two beautiful terrasses equipped with tables, chairs, a hamac and two transats. Perfect for eating outside. The communication with Ana was very fluent, we had all the informations we needed to get to the apartment and check-in went very fluently. Just be aware the street can get pretty noisy on weekends due to the bars. As young travellers it wasn't disturbing at all, we even enjoyed it. But I can imagine some people could be disturbed by it.
This is a great apartment to visit Porto, I would recommend it to everybody !
