I was very lucky to find Martha on airbnb... I lived with her for 2 months and a half and I have nothing but good things to say about her. Martha is one of the sweetest person you will ever meet, she is not only a host but she definitely goes out of her way to help you with anything you need. She is always very attentive and very welcoming. Her home will become your home because she makes you feel very comfortable in it. The room I stayed in was the smallest one in the apartment, but definitely does the job... It has cable TV, a single bed, a fan, and enough room for your clothes (but it doesn't have a closet) the Internet goes in and out sometimes but Martha is working on it...
If you decide to stay with her I know you won't regret it. You will make a new friend and feel like you are at home.
