We stayed in Amilcar's apartment for 5 days and it was the best experience you can possible get using airb&b. Amilcar is very friendly and hospitable, he really went extra mile to make our stay comfortable. when we needed to get any help from him or just some information about Buenos Aires he always tried to respond as soon as possible. The apartment itself is very very nice clean and has got everything what you can possibly need. We really felt like home (and its not easy to satisfy 3 gilrs)))). Location is also great - there is huge night life in Palermo district, if you like jazz or night clubs or just having a drink in a bar - there are plenty of places in walking distance. its a little bit far away from main highlights but there is a subway station near by or you can take a bus. As for us - sometimes we just walked. We loved Buenos Aires - but Amilcar made us love this city a little bit more)
