I stayed in the apartment for a little over a month very much enjoyed my stay. Martin and his family were great hosts. I was met at the apartment and given a tour and pretty much left to my own devices, which is exactly what I wanted. Martin checked in periodically to make sure everything was ok.
This was a great apartment exactly as described. It is a good size and was perfect for me. The kitchen was well equipped for when I cooked. And being in Palermo I was spoilt for choice when I wanted to eat out.
The wifi worked perfectly as did everything else in the apartment. There were no issues at all during my stay.
I would definitely recommend Martin's apartment if you are visiting Buenos Airies.
