Ilse's apartment is very lovely, in a great location and wonderfully decorated. About a 10 minute walk to the metro, with lots of great restaurants and bars around. The apartment is perfectly safe after the earthquake. Like most apartments in Mexico City, you use a key to lock the door behind you, so keep the keys in the door should there be a reason to quickly leave.
Definitely check out her food/bar recommendations, they were great! There's also a juice stand on the corner with amazing juice for only 15 pesos!
Take note, light sleepers, there is an upstairs cat who likes to sing and the walls are quite thin, so neighbouring music/voices can be heard.
