It's really the best choice for a single traveler to visit Porto, especially for girls.
Hosts are really nice, they offer me the local wine and recommend the good spot to visit in the limited time.
And the room is so cozy and tidy~
I have to say the location is best for people, near by the Harry Potter book store and just take 2mins to the Saobento train station.
All in all, it's a good choice for you!
