San Telmo is the perfect place to stay for those who like charm better than sumptuosity as it is the antiquaries Quarter with all the Great restaurants (strongly recomend Desnível, only a couple of quarters away from the apartment) and charming bars to have a glass of Malbec red wine or a cold Quilmes beer.
The apartment is beatifull and the location is perfect to explore the amazing city of Buenos Aires.
The apartment is as confortable as photos show in a Great building and very well decorated. I strongly recomend it and would stay there If I would come back to BA
