Stayed there a couple of years ago. Was in need of attention then especially around the pool area. Room was fine but if you get one at the back you will seldom see the sun from very small balconies. Turkish breakfast. Mostly Turkish staff who did not speak much English (not a criticism). Mostly German and Turkish guests.
vizon hotel doesnt have a pool, vizon hotel is in fethiye, its partner hotel grand vizon is in calis
my partner works there, i agree very german based!
vizon hotel i dont know, never seen the rooms, just the lobby lol but we're friends with the staff and i dont think they speak much english either
