I stayed in sunny room for 10 days. Apartment is really good lockated, everything is like on the pics. However, it was not as clean as I expected, but it was not so dramatic. Also the host was helful in the beginning and gave a lot of recommendations and tips, but by the end of my stay he was not that friendly and helpful, especially with check out.
As for the serfing lessons that are offered in this house, it was a failure. For 10 days there was only one lesson in my last day in the city that I wasn't able to take. But there were a lot of excuses. I had a feeling that this process is poorly organized and that one person is not treated as a customer in this house.
