This was a great place to stay in Porto. It is on street next to the train station (literally a 1 minute walk), and it is quiet and peaceful I spite of the busy location. It is above the Ribeira and about a 15 minute walk up-hill from the more local flavor of the neighborhood of Cedofeita. It is about a 20 min walk across the bridge to Gaia.
To wind down, they have a nice balcony and a smart tv. The shower loses hot water quickly, so keep that in mind!
Highly recommend the stay here.
