Ivy's place is in a great location and the apartment itself is very nice. The private terrace is lovely and apartment is comfortable. The building felt very safe and secure and the doormen and other tenants were friendly. There is so much great food right out the door most people probably won't use the kitchen. Because we stayed a full week we did and found it met our needs (just barely). I traveled as a couple who stayed for a week and worked part of the time. The internet worked well and they was plenty of space for us to have separate work areas.
The neighborhood is very centrally located. Having stayed in Condessa, Roma and Centro previously, this was the easiest location to get anywhere on foot in 30-50 minutes. We walked to the Zocalo, Chapultapec park, Condessa and even Polanco (Soumaya museum is a must-see!). Sometimes with traffic it wasn't worth the (affordable) Uber ride so we just walked. Rio Lerma and Rio Panucho are the main dining areas, but we enjoyed walking north of the apartment into the neighborhood where there were many bakeries and cafes, an organic food store, and cheese shop along with very affordable local taco and torta shops. Destacado was one of our favorites, Pantastico for great pastries, Chetitos for tasty and creative tacos (but hard to get into on the weekends).
