We ended up staying in another house owned by Maria Laura at the same location.
Near Recoleta Mall and a lot of streets with restaurants close. Close to the metro and supermarket, it was an excellent location.
It has a lot of noise when the metro passes but for us was not a problem :)
Maria Laura is a good person and gives you a lot of tips. Very helpful and nice :)
If we return to Buenos Aires we will talk to her again for sure !
