Mechi & Javi were very hospitable and accommodating.
Communication was great, they were always responsive.
The apartment and the area is clean and safe.
The area is very trendy so if that's important for you and it is what you are looking for and willing to pay the price for it, you will not be disappointed.
Noise could be an issues if you are sensitive to it (I am overly sensitive, I admit). Everybody has dogs, they are all over the place in this neighborhood, including what's left behind the dogs. If you are a pet person, you will love the area. If you are not, you will have a hard time.
Transportation (public) and taxi is not a problem, but it is good almost everywhere is Bs.As.
Mechi & Javi were very flexible and correct, I highly recommend them as hosts!
