I had a great four night stay at Ruben's apartment. I already know the question you're going to ask, and the answer is yes, the balcony is AMAZING. Condesa is the best location to stay in Mexico City...more tree lined than Roma but even closer to Chapultepec and so many food options nearby. The one thing I did not like about the apartment was the bed; it was far too firm for my liking and I ended up sleeping on the couch every night. I'll be back in October for the f1 race I hope!!
