Carolina was a welcoming and helpful host from the second I arrived until I left. She waited without issue for me when I arrived later than expected (1am) and went beyond what I would expect of a host in voluntarily calling the airport/multiple airlines as my baggage still hadn't arrived 24 hours later.
Carolina was helpful in giving me guidance on what to do and see (for someone who hadn't planned a single thing that was a huge help) and she was very responsive, with a warm personality, throughout my stay to the couple of questions I had.
The apartment was perfect for me (a single male travelling on my own) and the main positives were cleanliness/abundance of towels/aesthetics/AC units/space of the bedroom and living area (I used the 'hallway' as a small workout area) and last but not least the location.
The kitchen was adequate with a good size fridge/freezer and a gas cooker, I'd missed that there was no washing machine but that was my bad (Carolina pointed me to a laundry 50m away and they turned my things around in 3 hours which was actually better than doing it myself!).
The only notables on the less positive side would be that the patio is fully enclosed and gets almost no sunlight or airflow, no issue for me but if you plan to sit there on an evening then it may not meet your expectations and the shower is particularly small, I'm slim and it was a squeeze.
Overall this booking, both the accommodation and Carolina as host, more than met my expectations. If I get back to Buenos Aires, and I do hope so, then i'd book this again without a second thought.
