Ana's apartment is perfectly located to visit Porto. We didn't need to take the metro anywhere, it's so central.
Ana was incredibly helpful and very flexible with check in / check out times so we could leave our luggage at the apartment and enjoy the city on the 1st and last day.
The apartment itself is spacious, the bed comfy, the lounge has a cute balcony with a table and chairs to enjoy an early evening drink.
I would definitely recommend this apartment!
