My partner and I had a really great time in Porto. The apartment was very well kept, clean and well decorated with good views of the square. It was perfectly placed for walking to everything we wanted to do. The furthest we had to walk was about 4 miles to the botanical garden. But, walking through a new city is no bad thing. We walked no more than 20 minutes to restaurants (vegetarian, but I'm sure there were meat ones too) and cafe's and the river. There is also a food market around the corner and a supermarket.
Throughout our stay, Rosa, the host, was welcoming and helpful. We definitely felt if we needed to that she would provide help or information. This apartment is well worth staying at for location and aesthetic and for feeling at home while away.
