Martha is a very friendly and social host, who receives you always with a smile and give you some recommendations about where to go in Ipanema. She is a really kind person.
I think the room is smaller than you see on the pictures, but if you are looking for some place only to rest, is good for you. Martha let you use the other rooms of the house, like the kitchen or living-room.
If you are looking for something near the beach and the center of Ipanema, is a good option.
