Gwen's apartment is good enough for me to stay in Zurich. The apartment room temperature is high in the summer day time but at night the room temperature goes down if open the window. Other than that, everything is good for me. Gwen is a great host, she approach to me first when she find out Zurich might have heat wave, she call attention to me about her apartment might be too hot to stay, luckily Zurich weather is not too hot.
