The host Juan is fantastic, very helpful and always just a quick Whatsapp message away. He met me at the apartment when I was arriving and leaving for the keys which was really helpful.
The apartment itself is great, clean and well equipped it has everything you need and is only a short walk to a shopping centre with a big supermarket. Palermo itself is also a great place with lots of food options and things to see and do.
Next time I'm in Buenos Aires this is where I'll be staying... :)
