Ruddy's place is just as the foto's depict. It's a glass and stone lovenest. It's in an architecturally interesting mix-use building. Cafe Bruna is right downstairs and ecobici right in front. All convenience's are within walking distance including the Parque de Mexico which I didn't have enough time to really enjoy. La Condesa is, understandably, the most popular barrio on airbnb. I walked home at 11:45 at night and felt exceedingly safe.
The water temperature was an issue as described in other reviews.
