I booked this place for a business trip, and the location was quite convenient for me. César was super helpful via email and in person, and Luísa really does her best to make you feel at home – the flat is really clean, with nice smelling sheets and little cosy details (it made me feel like I was staying at my grandma's). As a bonus, I met a lot of interesting people who were staying/living at the house at the same time, so overall it was pretty nice. The one downside is that it is not very close to the Metro, and buses in Porto are not the most reliable (but Uber is really cheap and €10 will take you all the way to the Airport!)
