Mariana was an excellent host, and the place was exactly as described in the publication. The building is new and the neighbor's are also great. Some things to highlight:
--> Mariana always answered every question we made and quickly. With great attitude as well.
--> The place was very clean, and the rest of the building as well, since it is relatively new (a couple of years old)
--> There was plenty of recommendations on her behalf on what to do around. It is located in a good spot and pretty close to a few bars to go in San Telmo.
--> The place is relatively quiet (something not easy to find in Buenos Aires), so during the sleep was very good during nights.
I would definitively recommend Mariana as a host and this place to stay.
