Sergio's apartment is awesome! Four of us stayed here for four nights - and an amazing time in Buenos Aires - more so thanks to Sergio. He was extremely communicative beforehand, helping us to arrange transport from the airport. He met us at the apartment on arrival and gave us recommendations about local restaurants and bars. The location is brilliant. A very safe, trendy and tree lined neighbourhood with great night spots near by. The apartment itself was perfect - clean, modern but also very homely. The building has a nice rooftop pool and terrace where you can enjoy the stunning sun sets. All in all I have nothing bad whatsoever to say about the apartment or Sergio - perfect place and a perfect host. Highly recommended.
