Right in the city center, beatiful apartment with all the amenities you would like to have. The building is very secured, with security guy in the reception and locked main door. The neighborhood is very central, with a few minutes walk you can arrive in Plaza de Mayo, the main plaza of the building, where you have presidential palace and the Cathedral. Metro stop is just 2 minutes walk from building, you have also a good super market in 4 minutes walk over the street.
Apartment was super clean and everything was as described. Maria was super responsive and supportive. She even let us to checkout apartment a little bit late, because we had a flight in the evening.
Thank you Maria, hope we will be able to visit BA again in the future.
