Definitely recommend a stay here if visiting Porto!
The flat is in an excellent location, easy to get everywhere on foot.
It's clean and tidy, with everything you'd need including towels etc.
The kitchen is great with all that you'd need including fridge, cooker, coffee machine etc
Beds are comfortable with plenty of storage, and good blinds to allow lie-ins even with the sun shining outside.
If you're a light sleeper it can get a little noisy at times but if you follow the Portuguese weekend sleep pattern and have a mid afternoon/early evening nap, party til 4am then sleep a little later in the morning you're fine 😉
I'd recommend getting a map from the tourist office as they have more detail and we managed to see most things on foot on one day then did the amazing Porto bridge climb and people watching sat in cafes on the Sunday.
It's a great weekend city as you can feel like you've seen a lot and still feel relaxed but also if you had more time there's plenty to do including the Port houses, trip to the beach, ride on the river, art galleries, museums etc etc.

Again I'd definitely recommend staying here and visiting Porto!
