Palácio Santanna was an awesome place on my visit, I was planning to stay 5 days and I stayed 14 at last. Carlos is not just responsible for making the place spotless, but he is a rise of sunshine in your every morning: he makes sure all guests are feeling comfortable, is super hospitable and a kind heart.
The place has all you need: is close to everything but still in a quiet zone, the kitchen is very well equipped to cook, internet works really well for studying and working, is pretty clean all the time. Rooms are simple but pretty equipped with hangers and drawers, besides a desk.
The atmosphere of Palacio is very nice since most people stay for longer periods of time, meaning that you get to meet people and develop relationships.
