Well-located flat but very noisy, both from outside and inside the condo - very bad soundproofing, I had to patiently wait for the neighbor to end up washing the dinner dishes before being able to sleep, I had never heard such noisy taps in my life.
Transit outside is staggering, especially the "colectivos" / city buses, but this is the price to pay to be inside one of the Bs As best areas unfortunately. Cautious as well with frequent sewer smells in the bathroom, another frequent pain in Bs As buildings, as recent as they can be.
What is more annoying is the actual state of the apartment, much less glamorous as it looks in the pictures (broken furniture, spots everywhere on the carpet or on the walls, terrible image quality of the TV set...), very basic and sometimes rusty pieces of dishes (I had to purchase some basic items in the supermarket), and lack of host's human warmth. She routed me to her daughter without answering emails then, who herself did a minimum job, without any friendliness. She announced several times she would come over but never did. It would have been better not to announce anything therefore.
As a whole, a correct stay with regards to the price paid (half-slashed due to the pandemic, my stay was professional) but I would not have paid more money.
