This is a really nice apartment in a great location.
Spotlessly clean, the rooms are spacious and well appointed. Two bedrooms have en-suite bathrooms and the bathroom for the 3rd bedroom is right opposite.
The tram, bus and city-tour bus all stop at the end of the street, where there is also a supermarket. The cable-car and the Louis 1 bridge (top level) is 5 minutes walk away.
Remember that Porto is very hilly and although the apartment is very close to the river, it is quite a steep climb to get to the top level of the bridge. However, a taxi from the river only costs 5 Euro if you don't want to walk.
We would stay here again.
