Mario wants his guests to get the most out of their experience in Porto and he has gone out of the way to think of everything a traveler may need. Location is on top of a metro stop and close to lots of shopping plus Porto is very walkable. Even though I went all the way to Gaia I only used the metro to and from the airport because the city is actually quite easy to navigate on foot and is very safe. Great hot showers, comfy beds, secure building and room - thank you!
