Gabriel, our host contacted us soon after booking and was always very prompt in answering questions. He provided excellent advice regarding what to see and do. He even organized transfers to and from the property and was there to meet us when we arrived.
The flat was spacious enough for the 6 adults in our group and was well equipped for all our needs. Gabriel even provided a variety of food and drink products to help us get settled.
We were about a 10 minute walk from the metro which was then about a 5 minute ride to the Bento stop in old town. A small grocery store was right around the corner.
All in all we would not hesitate to recommend this accommodation when staying in Porto.
