We stayed in the apt for 10 nights and were very pleased with the price/quality. It is a big apt near of the Douro river. The seagulls started their "concert" early in the morning, but it may be usual also in other parts of Ribeira. If you are a light sleeper, the earplugs may be handy, though.
The apt does not have aircondition, but it was cool enough anyway, there was a little fan, but we didn't need to use it. We slept windows closed, and it was still nicely rather dark in the mornings because of the nice oldfashioned wooden windows.
The apt is not luxurious, but it has character! Beautiful wooden panels on the ceiling!
Luis was a very nice host, we would like to thank him for his great hospitality!
