I have stayed at this hotel on 3 separate occasions when visiting Buenos Aires for a weekend. The location is great as it is a 100m walk to many restaurants, bars, the cemetery and now to Recoleta Mall for shopping.
The rooms are very nice and clean, though some are a little small, I would book an upgraded room for the bit of extra space. Breakfast is excellent as is service. The pool is also good all year round as it is indoors in an enclosed garden.
I will definitely be back.
