Excellent place.
Location is great, it has shops for everyday groceries at the doorstep and walking distance from bigger supermarkets, bars and restaurants in Palermo. Also good buses & metro connections close by.
The apartment is very comfortable with all you need for a pleasant stay, specially if you are planning to cook by yourself. Definitely value for money compared to previous experiences in the region; we would stay here again next time we are in Buenos Aires, and recommend it 100%.
Mercedes is a s superb host, with great attention to detail and willing to make anything happen for you to feel welcome and comfortable.
