This apartment is amazingly placed right in the center of the downtown madness. You are up on the 6th floor with street views of the city and an incredible view of the Latino America Building (a great place to see the city BTW). There's always a door person ready to escort you up the elevator, the building is secure and must be opened by the guard inside.
The building itself is charming but full of quirks such as with glass floor/skylights, old style elevator and (mentioning for the sake of caution) very very slick stairs with no handrails. Make sure your shoes have decent traction. Especially when it's raining!
The only issue I had with this apartment was issues with the key code and the lock. They made note of it and mentioned it would be resolved before the next guests arrried. The delay caused us to sit around outside the apartment in direct heat with our luggage for about an hour. Hopefully this isn't any issue again!l for anyone else!
