Have stayed at this property before and would stay at it again. Good balance of location/neighborhood (Condesa, parks, restaurants, subway, buses), apartment size/amenities (spacious, newer fixtures, nice shower, in-unit washer/dryer, plenty of light, 6th floor + elevator) and cost (better than what you'll usually find elsewhere in Condesa). Overall a great value.
Both times I stayed at the apartment, they internet did have some issues, but communication with the host was prompt and quickly resolved. The host even offered me a free extra night for my troubles. Neighborhood is quiet at night, but there is construction nearby during the mornings and afternoons. I didn't find it to be too overwhelming with the windows closed, but if you're a light sleeper and want to sleep late, I'd recommend a set of earplugs.
