Alexandra's place was great for both my mom and I. It was the perfect homebase as you can walk to almost anything you need in Roma Norte - from oxxo, banks, shops, and places to eat. The apartment itself was incredibly cozy especially for 2 people and with the round the clock security we felt absolutely safe.
We did run into the issue of no hot water but after communicating the issue with Alexandra, she had someone there later that day to fix the water heater.
