It was a great stay at Danielas place.
Thay have a great sense of hospitality , we felt more than welcome and pretty much taken care of. Her husband picked us up from the airport,showed us around the city, and gave us good tips for your 3-day stay in Porto.
The appartment is very spacious, has a charming garden and is very confortable. we felt at home :-) the nearest metro station is 10min from the flat, 20min by walk from the center (easy coz downhill). Taking a cab can be more advantageous than takinh the metro, there is not a big price difference.
i would highly recommand it :-)
