I'm an American with a Czech wife. We live in our Prague house a few months out of the year, and in the US the rest of the time.
Our house has 2 other units with long-term renters. One of them (Asado) acts as the caretaker for the property, and will be your neighbor and point of contact for all issues.
Between the 3 of us we speak English, Czech, Russian, Belarusian, and Japanese. I look forward to hearing from you!
