I would (also) recomend you something between es Viver and es Puig. Es Puig is great if you like (often) walk to the city. Take the tunnel and you will be there quickly. You can also walk to PDB or take the bus (but be careful to chose the right one. One will drive a long detour through can canto and cas serres). If you want to rent a car, Es Puig is horrible for parking. Everything is short-term parking, or expensive car parks. Little hint: I always parked my car (for free) in es puig up the hill and never got a ticket or got towed ->

With the car you need to drive around and through the tunnel to reach it. But by feet its a short walk from the hotel back to the car

For the stay i would recommend you the LUXMAR Apt. Its realy cheap but you can have a great sea view, watching the sundown, and have a view over Figuretes until PDB
But if you are hungry and if you like to enjoy great food, the area around Figuretes is horrible. Expensive and realy low low quality. I would recommend you to eat in the town, or Prince of color in figuretes isn't that bad, or take a delicious burger at The booo
If you have more questions about that area, feel free to ask
