I've stayed at Claudia's apartment for a couple days and it was absolutely lovely. It's perfectly suited for a one person or a couple, got everything you need (including fast wi-fi which was important for my work) and is close to all the public transportation - and Avenida da Liberdade is also a short, 10 minutes at max, walk from the apartment.
Claudia, thank you so much for having me.
