Boris thanks for staying with us. We're sorry to know that the hot water ran out filling the large spa. We have turned the hot water system temperature up and from our test there didn't seem to be a problem. Although we will check with our current guest. It would be nice to know about the problem earlier, so we could have solved it. Wifi is available in the main building. Airbnb guests, we work hard to ensure your stay is wonderful, please let us know of any issues immediately so we can resolve for you.
