I had a very pleasant stay at Ada's apartment. This one is very well located just a couple of blocks from Madero Harbour and sorrounded by stores , restaurants, caffes, supermarket, etc.
The building is very secured and included a very well equipped gymnasium and a great outside pool. On top of that, there is a marvelous view of the "Rio de La Plata" through the balcony. Definitely a great place to stay.
