The place is nice and comfortable, stylish in a lot of ways, the passage where it is located remind you of the Buenos Aires you read in the history books and matches the San Telmo vibe.
The location is good if you want to go to San Telmo or Puerto Madero, some parts of the neighborhood look rough but it’s safe.
The only critique I have is the amount of noise (one night there was a Murga festival until 2am, the other nights parties all night long) and the amount of bugs in the apartment, from ants and beetles to silverfish, so if you’re concerned by this then I will not recommend this place, otherwise all good.
