Santiago is a very helpful, flexible and straightforward host. He provided a tour of the apartment and its amenities, and is friendly and kind. The apartment is exactly as described in the listing, is very comfortable and has all the amenities you'd expect from a penthouse in one of the nicest parts of town.
Location, location, location. Many of the best sights, restaurants and social spots are within walking distance.
Stay here without hesitation - great value! I'm only sorry we didn't make more use of the great balcony and parilla (grill) outside. The air conditioning is good and is delightful in summer when you walk in after a warm day walking the city.
