Jackie's place is located on Colonia Roma in a middle class residential neighborhood. Living at her place is an experience of being part of that local community. It is worth the USD13 you pay per night. Its not a place if you are looking for any hotel type or moderate to luxury stay. Its clean (however if I would do it again I would bring my own blanket and sheets). Its a good place if you are looking for a place to sleep and shower. Also, I would lock my belongings. If you decide to take the place, I would contact the host in advance and confirm the address via email (the address of the unit was mentioned wrongly on airbnb confirmation and the cab driver had to go back and forth till we got the host on phone).
Over all, if you are looking for hostel type of amenities (minus meeting travelers like you) like in a developing country, with the benefit of actually seeing what the local working class community is, this is the place for you.
