Great spot! The hosts were quick to respond to any questions, gave a ton of local recommendations and suggestions, and even messaged us to advise on bad weather coming through Porto. The apartment is really big and clean, and has a cool view across the way of a church. Its very close to everything and all the big sites in Porto, but also close to less touristy areas which have the best restaurants where the locals actually go! I believe there is a shelter across the street, as from about 6-8pm it seemed like there were lots of people lined up to get in basically right outside the door of the apartment, however it never felt unsafe. We would definitely recommend it!
