We enjoyed our visit to Christina's apartment in Porto very much. The apartment was very well situated and allowed for easy access, usually by foot, to all the main attractions in Porto. The view across the river was superb and we especially enjoyed the view early in the morning as the sun was coming up.
The apartment was perfectly clean and exactly as shown by the photos on the site. Also, it was quiet and we slept very well. The restaurant below the apartment was quite good, and frequented by families and locals. Also nearby was a very nice bakery for breakfast each day (coffee and a pastry). Inexpensive, local and very friendly.
Of particular note was the help Christina provided when we arrived. She spent a significant amount of time describing restaurants, transportation options, and sights to visit. This was very helpful, we ended up using her restaurant recommendations almost exclusively during our stay.
Christina was available on short notice if we had any questions or problems. All in all, she was a super host! Thanks Cristina for all your help, you made our trip that much more enjoyable.
If back in Porto, we will definitely stay with Christina if at all possible. Good luck in the future.
