Joao is a fantastic host who took the time out to show us the best things to do in Porto and where to go.
The accommodation is great, having 2 showers is fantastic and the beds were comfortable. It is also very central but the surrounding buildings block out all the noise.
Only slightly negative comment is that due to the buildings blocking out the noise, they also block out the airflow so it gets very hot. A fan or two would make the world of difference.
I highly recommend this place to stay while in Porto!!!
