Rodrigo's place is extremely well located. While I'm a local in Buenos Aires, I traveled with my family from the US and they found the location perfect as well. Walking distance to several points of interest, safe and beautiful architecture. It is pretty noisy, but considering the location, it is understandable.
The employees at the building are extremely nice and helpful as well.
In terms of size, as a family of 4 we fit perfectly.
Communication with Rodrigo was very easy, fast response and extremely nice.
