Do not think it twice amd book this right away! The apartment is at walking distance from pretty much every tourist, cultural or cpmmercial area you would like to visit while in Porto. It has a fantastic distribution of space and grest amenities.
The hosts have even gone out of their way to provide the guests with a handful of books, maps and brochures of what to do, what to see and what to eat while visiting the city.
The beds are super comfortable, the apartment is very quiet, free wifi is provided, kitchen is very well equipped, bathroom is great. Need I say more? I loved it.
