We stayed at Carol's apartment with my wife and our 3yo son for 6 weeks. The property is wonderfully located in the centre of the Belgrano neighborhood, with great transport links and plenty of shops and places to eat.
When we arrived at the apartment, we were made to sign a contract and a long inventory that listed all the items in the property. This was a first for us, after some eight years of using Airbnb in locations across the world. It was a bit tiring to have to read through these documents after a 17-hour flight with an exhausted 3yo, especially when you have your contractual agreement on Airbnb already. It didn't seem right to have to sign another contract in Spanish since we already had the Airbnb one, but there was nowhere else for us to go and we were pretty tired, so we signed.
The apartment was very well cleaned throughout: inside the cupboards and wardrobes, the bedsheets and kitchen utensils, everything was super clean (although we did find a couple of squashed mosquitoes on the ceiling). It has ac in the living room and two bedrooms: a must for a summer in Buenos Aires. It was well-equipped, although some things were a bit old and run down: for example, the mattress cover was yellowish and broken, so it would shift around permanently, making it difficult to be comfortable on an already very (very) firm mattress. If extremely firm mattresses are your cup of tea, you will feel right at home with this one.
We had a few issues with the refrigerator and the hot water, and the host replied very quickly and eventually sent a repair person who tried to fix it but the issues kept reoccurring. However, we were questioned repeatedly over whether we had left the fridge door open, forgotten the defrosted food outside the fridge or if we had been covering the refrigerator’s drain area. Also, the kitchen fan did not work, which meant that the apartment smelled like whatever we cooked on the day. We were told it came with the property when it was bought and that it would need to be replaced at some point. For both the kitchen fan and the fridge we were told they would have to be replaced but it didn’t happen during our 6-week stay.
The building has a pool, which we used a couple of times, and was great and a tennis court, which we didn't use but has no extra cost.
Overall, the location, price, and building make this apartment a solid choice when visiting Buenos Aires.
