I stayed on month and a half in the studio of Gipi and everything was great. The flat is very central in Palermo with many shops and restaurant around in Palermo Holywood, in addition the little swimming pool on the roof is perfect for refreshing in summer time. It is also a very good place to commute in the entire Buenos Aires with many buses and the subway at 5 mins walking distance.
Gipi is very "buena onda" and very helpful, she is very careful that everything is doing good and helped me with cleaning bedsheets and towels on a weekly basis. It was also great to share with her experiences of traveling in Argentina.
I will stay there again and warmly recommend this place for a good experience of BA!
