We have visited Kalif 4 years ago in September. This year we have spent there 11 nights/HB which we payed 280€ and once again we had great time there. Hotel is in quiet street, it has own beach only 100m far. Our room was at 5th floor so we had great view. Room was cleaned every day: clean towels, new soap, toilet paper... Every room has AC, minibar, bathroom, tv, hairdryer and phone. Hotel also has 2 elevators, restaurant, pool, WiFi, ping-pong and modest fitness room.
We had breakfast and dinner: between 15 and 20 meals every day. Breakfast: eggs, different types of cheese, salads, olives, salami, jam, honey, cornflakes, tea cookies, bread, tea, milk, coffee... Dinner: every night chef served Turkish specialities. Food was different, from cold appetizers, soups, salads, fruits, pastas and of course sweets. No one will leave restaurant hungry.
Stuff is friendly, some of them are speaking Englih, some German, some Serbian. They are always ready to help.
Naighborhood is peacefull and quiet. Also safe. Main street is closed every night from 20h to 8h next morning. There you will find a lot of bazaars which work till late night.
Go to City Market across the post office.
You can also visit Ayvalik. Mini bus goes every 15 minutes and costs 2,50TYL (1€-2,2TYL). There is no need to go to the bus station, you can stop the bus everywhere you want just raise your hand.
I can also recommend day trip to Lesvos (Greece). Return boat ticket costs 30€. Boats leave Ayvalik port every morning at 9h and leaving Lesvos at 19:15h.
Be carefull, temperature is high, it was between 45 and 50°C. Sea is extreme salty, clean, full with fish and cold.
Enjoy!
