Sonia's place is very good value for the price - I stayed at her place one night, check in was easy, she was very flexible on the checkout time, the apartment is in a very nice, gated, complex, right next to conolly train station and about a 15min walk from the city center. Her roommates were nice and explained a few things as Sonia is renting the room out when she is away. Communication via the airbnb chat worked perfectly with her though!
