My friends and I (a group of 9) were staying at Maria's place for a bachelor party weekend and our expectations were definitely met. Tiago surprised us with Pastel de Nata and some other welcoming gifts, as well as helping us out with our questions regarding activities and locations around Porto.
Although being quite at the limit with 9 people, we felt comfortable and also enjoyed the outside area a lot. The place was clean and well equiped.
The location was a 25min walk from Porto's center, sometimes we decided to travel by Uber as it was quick and cheap.
We recommend this place for bigger groups like us.
