We stayed in claudia's apparment for 6 nights. First and foremost the apartment is secure and well located. Not slap bang in the heart of palermo so if your looking to be bang in the centre this apartment is a few blocks out.
The apartment itself is bright, clean and has everything you need for a short/long stay. There is a handy man and cleaner on hand to help with anything you need (Spanish speaking) and claudia herself is very welcoming and quick to respond if you do have any issues.
We thoroughly enjoyed our stay, we lived Buenos aires and the apartment was really part of that.
