Letter Written in Polish?

[Mickelow]

Witam,

I have a letter that was passed along to me from a family member.

I believe it is written in Polish.

Could someone be so kind to help with translating it.

Hereby, I confirm that Marja Demiec [?] has served at my house as cook - hostess for 2 years. She fulfilled her duties very well, she cooks very well, she can wash and iron nicely. I can recommend her as an honest, laborious, calm and willing person. She leaves at her own request.
