I stayed over at Mandy and Yu's lovely appartment for business and enjoyed it very much as it was a 5 minute walk from the conference center in a rather quiet street. The appt is completely renovated, sparkling clean and stylishly decorated. It also has a nice size for 3 people. Despite being close to the Ponte Abril 25 bridge with airplanes flying over, it is extremely quiet inside. Mandy and Yu are highly attentive and responsive should you need any tips or help but they still respect your privacy. The neighbourhood is a bit further away from the centre but close to a cool hipster place Lx factory and the Alcantara docks so there is always an opportunity to head out in the evening. Would recommend!
