Three words to describe Gustavo's apartment in Palermo : "Location, Location, Location". Everything is nearby meaning walking distance : excellent restaurants, supermarket, shops, bars, subte -subway-, buses, etc.
Gustavo is a super host. He took care of us at our arrival at the airport. A taxi driver was waiting for us. He was present at our arrival at the apartment. He offered us a bottle of wine as a welcome gift. He gave us a lot of information concerning the neighbourhood. He allowed us to a late departure without any cost.
Briefly speaking, we would stay at his apartment when Monique and I will come back to Buenos Aires.
