We spent four nights in Pedro&Irene's place and we really enjoyed the apartment. Everything was great. Pedro met us in front of the apartment at appointed time. He was very kind and friendly and gave us very useful tips about what to visit, where to go and what to eat in Porto. Also during our stay he was available for any questions and tips we needed.
The apartment and the room have everything you need for a pleasant stay . Kitchen is full equipped, bathroom was very clean. For me the best thing was a little terrace which is perfect for morning coffee and rest after sightseeing all day.
Location is great and you can easily reach everything by walking.
I really recommend this place.
