The apartment is very stylish and has a perfect location in the Ribeira. We stayed for 4 nights and had a great time in Porto.
We traveled in early spring, and it is worth knowing that it can be quite cold at night, so it is useful to bring warm clothes outside of the summer season. Because it is in the middle of the city, there can also be some noise in the evenings and early morning, though it was quiet at night during our stay.
There are grocery stores and bakeries nearby, and the apartment has everything you need to cook small meals. It also has high speed Internet and Netflix if the weather is bad.
The fish restaurant on the ground floor of the building (Taberna dos Mercadores) is also wonderful, but be aware that it is very small, and reservations are highly recommended.
