If I have to choose one word for describing this place, I would pick up "Perfect!".
The host, Barbara is amazing! She seems to know everything travelers want. Perfect location (very safe & a lot of beautiful cafes, restaurants, supermarkets just around corner), perfect bed (clean & spacious), perfect bathrooms (yes, there are two! one has a tube!), free Netflix & Youtube, salt, pepper and oil, and even some coffee & tea.
Wide terrace & clothes dryer! I really enjoyed myself at this place.
Next time to Buenos Aires, I definitely stay here again. :)
