10/10 on all levels. This location is prime for accessing everything in the heart of Porto. The description is extremeely accurate; it is 2 minutes walk from some of the finest restaurants in Porto, 5 minutes walk from the Douro water front and Louis I Bridge, 5 minutes walk from Sao Bento Train station, as well as many of the sight-seeing/tours offices.
Pay attention to the warning that Porto is hilly with cobblestone streets, so pack comfortable shoes. If you are into running, down along the Douro river is prime for running.
Carolina and her team are extremely responsive and accommodating; the response is usually timely and the transfer option to and from the airport is the best.
If we ever visit Porto again, this will be our place to stay.
