We enjoyed our stay in Condesa, the apartment was in a perfect spot for exploring the city and enjoying the park next door.
The apartment is generally quiet though there is a restaurant next door that plays edm until about 11:30 each night. Check is easy and seamless, and is always a doorman at the building to let you. Our one issue was there was a persistent sewage smell from the shower that is adjacent to the bedroom. It was bad enough we skipped showering one day. Otherwise the place was clean and comfortable.
