Highly recommended - both Maria and the place are great! Everything was done to make the booking as easy and flexible for me as possible, and Maria was great with communicating before and during my stay. The apartment is cosy and the rooms feel like they could be your own bedroom. Maria provides everything from a flash light to a Sube (public transport) card you can reload, and the size of the room is huge, with a desk, cupboard, bedside table and locking door for privacy. The shared spaces and bathroom were also excellent. The location of the apartment is just a few minutes away from the heart of Palermo so it's very easy to stumble upon a lot of cool cafes, shops and restaurants. Security here is also very good. I wish I could have stayed longer and will definitely be back on my next visit to Buenos Aires.
