I stayed nearly two months in Ximena's apartment, and it was a great choice for three reasons:
1. The location is walkable to many good restaurants, shops and services. You'll be walking distance to both the Zocalo and Chapultepec Park with all their museums and sites.
2. The apartment itself is comfortable, well stocked, and nicely furnished.
3. The building has some amazing amenities. Normally, I mostly ignore these at a property, but in this case I used them often.
Ximena and her husband are great hosts, and I look forward to staying with them again.
