I definitely had a great time at Gabriela's apartment! In a group of three, it offered us more than enough room to place our luggage and all the equipment worked fine, even though not much of it was used. Bedrooms are comfortable, as well as the living room and kitchen area. It is adapted to the Argentinian/Australian and also to the thinner European powerplug standards on the walls, reason for which I personally needed no travel adaptor at all. Other powerplugs might need adaptors.
Just a few blocks away from Rivaldia Ave or Corrientes Ave, therefore it has easy access to the local underground or Subte. Also not too far from the Obelisque, about 25 minutes away walking on slow pace. There are several cafés, kiosks, pharmacies and small supermarkets nearby.
Price was really fair for what it offered as a whole.
