We stayed in Porto at Fred and Maria's place for 3 nights. Porto is a beautiful city and Fred & Maria's airbnb is the best place to stay. Check in was easy. Fred walked us through the house and garden. He took out a map and guided us on what to see and where to eat, shop etc. That was very helpful. The house is in close proximity to shopping, museums, wineries etc.
The view from the house is very beautiful, true to the photos posted by them in airbnb posting. All the amenities were great, and they took the extra effort to list the Portuguese and english channel numbers available through cable TV. This shows their passion for hosting and making sure the guests are comfortable. We would definitely recommend Fred & Maria's place to anyone thinking about visiting Porto and staying in an airbnb.
