I stayed here for a month. I recommend everyone in the world should stay here. Its a lovely flat, very comfortable, sparklingly clean, in a great location and the joys of the lift with its shiny brass controls took me back to to a different era. I loved it.
I should say something about Marcella. She really is someone special and by far the most considerate, caring and generous host I have met while staying at AirBNB places. Nothing was too much bother and her knowledge and willingness to share the Bueno Aires experience went beyond the normal. If you stay here you will love it!
