Humberto,s place was everything we needed for our stay in Gaia/Porto. The apartment had everything we needed and Humberto provided us with extra help (clothes detergent) and water. The apartment is located in a very cozy street with sea food restaurants and fisherman houses. At night there is no noise and it is a very safe and calm street.
For us the easier way to get to Porto was using Uber and the ride from the house to the center of Porto was around 6 euros.
