First of all, Cláudia is an amazing host. She is always helping with your needs and know everything you wish about Lisbon - with the plus of her personnal view of the city.
The apartment is also great. It is very well equipped, has a stuning view and this place is near most public transportations and what else you need (supermarkets, restaurants, drugstores, bakeries).
Anyway, I recommend this remarkable place for anyone who wishes to visit the seven hills city. I certainly will again.
