Silvia is great. Very friendly and warm personality. My flight was delayed by almost 4 hours and she waited late into the night to let me in. CDMX is very cold for a tropical baby like me, so she lent me ponchos. She recommended me good places to visit around the neighborhood and downtown. The place itself is right by the metrobus station, on a tree-lined street in Roma Sur. Very safe and I walked home many nights feeling completely safe.
