Enjoyed a two night stay which was very comfortable, with friendly service, a great buffet breakfast and our room although fairly small was very clean and had a lovely hot powerful shower. The area is in one of my favourite parts of the city and near to the hotel are bars and a convenience store which was very traditional and had a good selection of foodstuffs and general items. Very close to the main shopping area and metro San Martin. I stayed in the Sheltown near Plaza San Martin in Buenos Aires so I am not sure if the Hotel on the featured address and photo is the same one as there are more than one 525 Sheltown in Capital Federal.

Clean, small rooms - but enough space.
Stayed in a triple room. Did have some issues with the safe in the room and communication with reception.
Walking distance to shopping,tourist information, laundry, restaurants, main streets.
Breakfast - very limited. Sweet bread, sweet cordial, sweet croissants (a sweet breakfast!)
Overall a good hotel for the price and proximity to the city.

The hotel is well located, especially if your planning on doing shopping, because its near lots of outlets and Florida Street.
The rooms are not great but they are clean and well maintained. The best rooms are those above the 7st floor, because of the view.
The breakfast is very limited but the options are very tasteful, especially the croissants!
