Nice apartment, clean, quiet. The hosts were very kind and flexible with check in and check out times. Good window seals so no noise from the street. Wifi is good, and there's heating. You've got all the essentials you need in the kitchen, although no spices and oil, but you can cook a nice meal. It's a little smaller than what it looks like in the pictures, but a great size for a single person or a couple.
Good location, close to many great restaurants, parks and other attractions. This is the commercial area of the city, so you have a lot of shops. Porto center is not far and easily accessible
Note that the piano is locked, in order to reserve its quality. But If you are a musician and ask for it, Antonion will open it for you. it's a good piano, tuned and nice touch. It's great to be able to practice while travelling!
