Some years ago I spent a week in Melia Buenos Aires , now I came back for a 5 nights stay.
Obviously the hotel mantain some strengths : situation very central with a lot of restaurants near the door, Florida street in walkable distance like Porto Madero, the rooms are very large ana confortable, the staff is still kind.
But there are some important differences. Furniture beguins to be something tired and old fashioned.
The bar in lobby that had some years ago all afternoons a pianist now has noise, in terrasse we wait large time to order and another large time til something reach.
The breakfast now is a very poor one without sufficient variety,Croissants that were terrific are now simply regular.
Conclusion: still a convenient hotel but declining.
