Lovely place. On the 10th floor overlooking Retiro station. With the window open it can be noisy but what can you expect with a prime location. For the rest no issues. Fantastic communication with the host and within 3 blocks there several good cafes for breakfast / coffee. Skip Starbucks! Hosts have a stack of tips ready when you arrive, and sent me tips on where to go grocery shopping and get laundry done.
Oh, and theres a pizzaplace right below the building thats well worth the visit, good pizzas, nice staff and fantastic empanadas.
