Casa 821 Guest House

Twenty-four hours of staffed security and a key-access entrance signal that Casa 821 takes its adults-only quiet seriously — the guest house occupies a colonial-era building on Calle de Carlos María Bustamante in Oaxaca City's historic centre, within a ten-minute walk of the Zócalo and the Mercado Benito Juárez.

Rooms include private bathrooms, hypoallergenic options, and fan cooling suited to Oaxaca's temperate highland climate. Upper floors are stairs-only, worth flagging at booking. A rooftop sun deck and outdoor fireplace give guests a communal perch above the neighbourhood's terracotta rooflines without leaving the property.

The address suits slow-travel couples or solo visitors using Oaxaca as a base for the Sierra Juárez villages or Monte Albán ruins, with concierge-assisted transport and express check-out keeping departures smooth.
