We had a great time in Porto thanks to Helena. She was a very organised and efficient host, and made sure we were well-equipped on our stay. The place is clean and is located centrally in a well-maintained block. Everything was working and the house was stocked with the expected essentials. It is a bit smaller than the photos would suggest, but it certainly wasn't a problem. One minor note: a rooster lives next door and crows very enthusiastically in the mornings! Just be prepared to sleep in a little.
