I am really grateful to Margarida.
Her place is really beautiful and very comfortable. And when I checked- in, she explained about some place which is important for trip in detail.
Also, she gave me a guide book in my language.
The location is great. But, one thing you make sure is that you should take an elevator from square to her place! HaHaHa
Actually, if I have some opportunity to visit Lisbon again, I want to stay here. I strongly recommend to stay here. Obrigado!!:)
