Phuket Racha @ Kata is great because it's close to everything you need, and tucked back on a quiet street. You can walk to the beach in 10 minutes. On the way, there are many restaurants, massage shops, pharmacies, etc. There is a nice open-air market nearby where you can get all kinds of Thai food & great, fresh seafood at a decent price.
The family that runs Phuket Racha @ Kata is very nice — friendly, helpful, accommodating, and speak English well. The rooms are quiet. The bed is comfy. The internet is fast enough for basic tasks. Free instant coffee is great because there is nowhere to get a good cup of coffee early in the morning around there.
This will always be my first choice when I go to Phuket.
