What a fabulous family to host you in Porto! Everything was simply perfect. Monica was waiting for us at the metro (that was a great surprise!) and she and her lovely family did everything to make us feel very welcome. They even brought around a Wii for our children!
We loved being just outside of the main city centre becaus eit gave us the opportunity to explore all possible routes in and to see the REAL Portugal, eat with the locals and discover the amazing cakes and pastries in bakeries away from the tourists.

We would highly recommend Monica's house. Don't be put off by the metro being opposite - it's electric and you cannot hear it at night. My husband and son are light sleepers and they both slept VERY well indeed.
In short - just do it! You won't regret it.
