We didn't realise how compact the city was until the 3rd day . It is easily walkable to all attractions . We ate at a restaurant 2 mins walk away called Flow and it was really lovely food and service . We went to the palace gardens and enjoyed a stroll around in the sun . Clergios tower and museum was interesting with excellent views over Porto . Loved the river area and the Port Wine tours. Sandemans tout was very informative and well organised .
