This is a wonderfully decorated place right in the center of Porto. It's ample big for two persons and as all the amenities you could need. We had a very wonderful stay here. The bikes are also a superb addition. If you're not afraid of hills, you can take them out and explore Porto with them - really awesome!
The one drawback was perhaps that the apartment is above the Starbucks which has music playing all day non-stop which is a little annoying. It stops in the evening though and doesn't start too early, but if you wanna relax during the day this is not optimal.
