I would highly recommend Graciela's apartment to anyone visiting Buenos Aires.
Firstly, Graciela is an excellent host and very accommodating - I arrived early into the city and she ensured that I'd be able to drop off my luggage at the apartment and then ensured that I checked-in earlier than expected. Likewise, when checking out, Graciela was very kind in offering a far later check out time if it was required.
The flat is high quality, a good bed, flat screen tv, comfortable sofa, akitchen with everything you'd need as well as extras such as a nespresso.
The building is excellent with a complete gym, outdoor pool, indoor pool, sauna / steam room and BBQ facilities.
It is in an ideal location - in a quiet street in Palermo but close to bars, cafes and restaurants.
Again, I'd recommend this to apartment and would like to thank Graciela.
