We've stayed at Ethel and Mirek's place for two days. To be honest, the stay itself exceeded our expectations.
They were both welcoming and Mirek really helped us anytime we needed.
The room itself is beautiful and spacious, so is the kitchen and the bathroom (if you are staying longer, you will surely appreciate the utilities).
During our stay we also met other Airbnb guests who were incredibly nice and friendly.
Highly recommended.
