My husband and I had a great stay at ULIV Condesa. The unit was bright and spacious. Furnishings modern. The kitchen had only the bare basics tableware and pot/pans, salt, pepper and oil.
Security aunties are the best. Extremely friendly and always greeted us with a smile.
I would recommend the host provide better instructions in gaining initial access to the unit and entering/leaving the building (what button to push to call,waving over sensor to exit). Luckily we know a small amount of Spanish so could understand the guards' instructions, I don't know if everyone else will understand.
It was easy to walk to most of the restaurants we had bookmarked within a 15 minute walk. We would stay here again.
