We stayed at Griselda's apartment for two nights. It was perfect for two adults -- I slept in the bedroom and my friend slept on the sofa/pull-out bed in the living area. It might be tight with more adults, but certainly doable. Griselda had a personal emergency so she wasn't there when we arrived, but she left the keys and instructions and check-in went very smoothly. The location is very convenient to public transportation (subte right next door) as well as very easy to walk to many areas. From the booking and up until we checked out, Griselda was very prompt in responding to communications. We had a great time!
