Helena was a really friendly host. She answered quickly to our messages! Check in was easy because she is actually living in the same apartment. The room as well as the bathroom were clean. We didn't use the kitchen - except for a coffee - but she offered us to use anything we needed.
We didn't know anything about Porto so unfortunately the apartment was not in the city center but within walking distance. We also found a lot of nice restaurants close by. In general it was a nice stay and I can recommend it.
