The apartment was very stylish and cozy. Though if you are the type to go to the loo in the middle of the night you will need to take the stairs down as the loo is downstairs and the bed is upstairs.
However, the location isn't ideal unless you want to go to cabalito which is about a 20minute walk away and it's not the prettiest walk. The metro is about 40 minutes away by walking. San Telmo is about 30 minutes away. I recommend using an uber to go out. If you plan to walk to Puerto Madero it is possible, though it is a bit of a walk and it's not the best walk as the roads are under construction.
I still managed to enjoy my stay, though going out is quite inconvenient and it is far from Palermo where most of the nice restaurants are. But it's good for going to San Telmo and Microcentro.
