I did my investigations and found as you said two Pigale hotels in Kusadasi :
- Pigale Panorama a 4 stars hotel situated near Kusadasi Centrum
- Pigale Beach Resort, 3 stars, abt 5 km from Kus, in Kustur.
Didnt find any with the 'sunset' though, but think the first one is your hotel! Maybe the name has changed, and there hasnt been any update on internet...
