I would definitely recommend Claudia's place to anyone looking for an apartment in Buenos Aires. First of all, the location is really excellent. You are within easy walking distance of the bars and restaurants in Palermo without having all the noise on your doorstep. The neighbourhood is quiet and safe.
I have stayed in many apartments in Buenos Aires and I have to say that this was the quietest of all of them. It was really great to be able to have a proper night's sleep! The bed is comfortable too. The apartment was clean and as shown in the photos. Also, the kitchen was much better equipped than most Airbnbs which is great if you like to cook.
Finally, Claudia was always helpful and quick to respond. Overall, a great stay!
