Overall a good place to stay. Some other comments about the highway noise are accurate, but if you bring some earplugs for sleeping and keep the windows closed it's not so loud that you'll have an issue
Mr. W wasn't very available via message, I asked for toilet paper and a frying pan for the kitchen but never got a response from him.
Location in Condesa area was great, close to Chapultepec, and there are lots of restaurants and coffee shops within a very short walk. It felt very safe overall (there is a doorman for the building too).
