After a few days downtown Porto, it was really nice to just stay at "Porto Natura House" in a secluded place. We, a couple with a baby, lived downstairs. The kitchen is great and has more than basic equipment. The bedroom was very cozy, the bed very comfortable and the whole room could be darkend to the maximum (which I prefer for a decent sleep). You can hear traffic from the highway close by but that was not an issue.
The bathroom and the toilet are small and there's hardly any space for placing stuff but that didn't bother us much.
We enjoyed the whole stay and recommend the place :-)
