The location of the apartment in Porto is unbeatable.
From there you can easily explore the major tourist attractions, have a drink by the river and find some delicious late night restaurant all within a very short walk of the apartment.
There is also a great bakery literally at your door step (and two more just down the road).
The apartment was clean and very pleasant.
As others have pointed out the building's old nature and busy central location means there can be a high degree of noise bleed but with a cheap set of foam earplugs at night this wasn't an issue for us.
Sofia and Ernesto were very pleasant to deal with and they were very reliable in communicating everything with us.
