Under the landmark dome of the Edificio San Felipe y Santiago, a rare survivor: a 1925 apartment kept fully original. High ceilings, ornate plaster moldings, stained-glass doors, parquet and patterned cement-tile floors, dark-wood boiserie — the period intact, room after room. Kitchen and bathrooms remodeled for modern comfort, discreetly and in keeping. Bright, north-facing rooms open to the avenue. Offered turnkey: available fully furnished for an additional USD 10,000, ready to live in from day one. Artwork not included.
