It was an absolute pleasure staying at Peter/Engin's. They are extremely responsive and helpful. When I first came into Zurich, they provided detailed instructions on how to reach the address which was well appreciated when jetlagged and disoriented with a new location. The room was extremely comfortable and had beautiful views. The location is fantastic, a 10 minute walk from ETH campus. Could not have asked for a better place to stay while in Zurich.
