Yes, there is nightclub noise as the review states, but the earplugs that Julieta supplied were great quality and the bed is so comfy that we slept very well.
The apartment is lovely with huge windows and oak trees outside; and within walking distance to many amazing restaurants and wine bars. The nightclub scene at Niceto was one of the highlights of this trip - we went to an event at Club69 which was AMAZING with dancers and great vibes so if you're lucky enough to be staying here when there's an event, GO!! You won't regret it. We would definitely book here again when we come back to Buenos Aires.
