Tania's house is the same as it shows in the pictures, very clean and spacious room. She's very kind and friendly in every moment, if you need something you can send her a message and she will answer immediately.
There are some things to keep in mind, you share the bathroom and the kitchen with 3 rooms more, so if those are occupied it's a little uncomfortable spend time there if you don't like much people. You also have to consider that most of the time the bathroom isn't available. Cleaning is very good, there's a lady who do it every morning, but it's a shame that not all the guests keep it clean, of course this is out of Tania's control.
It's a latin neighborhood, not too pretty but is quiet and safe, two blocks away from the metro station and there's a lot of markets and stores around.
