Had a great stay at Guido's place for more than a week. The apartment is as pictured, clean and located in a good/safe neighbourhood with public transport nearby. Got to meet both Guido (briefly) and her mother (who helped me to check in and also showed me around the Recoleta neighbourhood). Small note that as others have mentioned there is some street noise that might bother light sleepers. But for me it is an apartment that I would easily choose again if I were to return to BA.
