I chose this place because it was relatively cheap. It was the best decision I made this weekend.
First off, location, location, location. The Villa Sonata is five minutes from the Cleopatra Beach (the good one), Damlatas Cave, and many nice cafes and parks. I stayed in a twin room- comfortable beds and working A/C. No view from the bottom floor but who really needs that when you have two pools, a breakfast area, and a rooftop terrace- all with panoramic views? Rooms also had a living area with comfortable couches and a kitchenette. Bathroom was modern and clean, water pressure good and plentiful hot water. Only small problem was Wifi- it had a strong signal from the toilet and part of the hallway, but not in the bedroom or living area (I think my room was furthest from the hotspot).
Breakfast was included with my fee but read the fine print because sometimes it isn't. It was a standard Turkish breakfast- vegetables, cheese, tea, bread/jam, and an omlette. It's light but filling. Make sure you have bottles of water on hand because Alanya's tap water isn't drinkable but it's fine for brushing teeth/showering.
Staff were excellent and extremely helpful.
The one issue with the hotel being part way up a large hill is that it would be difficult to stay in if you have mobility issues. It's a steep climb and taxis to/from the beach aren't very practical. For younger travelers/couples/families, it's the perfect spot.
