We had a good stay at Sisus, as a break from Istanbul and Izmir. There were very few guests at the hotel or in this part of town in mid-November. The weather was good, so we enjoyed not having to deal with hordes of tourists. Many restaurants and some hotels were closed, but Cesme was still a pleasure to walk around and plenty of shops and restaurants were still open.
Our room was modern, clean, and comfortable. The WiFi worked well in our room.
We had a bit of a dispute with the hotel because our email from hotels.com said we were entitled to a free breakfast, but the hotel said that was incorrect. The hotel manager kindly allowed us a free breakfast on two mornings anyway after we showed her the email from hotels.com.
There are a few decent restaurants across the small bay/marina from the hotel, where one can also get an inexpensive mini-van ride into Cesme or all the way back to Izmir. There are also a few convenience stores within a few minutes walk of the hotel.
