Nice apartment: clean, in a clean building. A bit noisy at night due to passing cars, neighbors, etc. (but I guess every place in Mexico City is!). One real bedroom for parents; one nook with two bunk beds plus a futon for additional guests (up to 6 total). Conveniently located: very close to the Isabel la Catolica metro station, or a 15 minute walk to the Zocalo through the historic area. Also plenty of bars + restaurants in the streets that are perpendicular to Isabel la Catolica street (one block north and south). Best to know some Spanish to communicate with the landlord lady via WhatsApp. Has Wifi.
