It is a nice place and a fantastic location. Oscar put a great personal touch to it to make it feel like home.
Downstairs right beside the entrance is a very small restaurant also open for great and reasonable priced breakfast.
Keep in mind, that the city has plenty of cultural offers. Enjoy the opera or have a incredible time at the ballet folklorico.
La Condesa is a nice and very safe area with plenty of different restaurants, even German style at "Volksbier" or "Frankfurt" in walking distance.
You will for sure enjoy your stay at Oscar.
