Where is the best place to stay in Phuket, Thailand?
Looking for something reasonable but nice. The budget is under $ 100 USD per night. Search specific hotel suggestions and / or stay close to good beaches.
If you are thinking of going in the near future then you should get good value for their money because it is the offseason. You will see some rain at this time but would be very unlucky if it was rain all the time. More likely to happen in September / October there are two "tourist areas in Phuket and silent retreats. This variety is one of the strengths of the island. One of the best beaches of the island's Pansea Beach. Here is the Chedi Phuket. It's a bit more than your budget, but you have some extras included at this time. Nothing much here, but the bright lights of Patong is about 20 minutes south. Another to consider is Mom Tri's Boathouse at Kata Beach. This beach is a good alternative to Patong. There are shops and restaurants, but is more discreet than Patong. Even if you do not stay on the pier, which indicates that this is a good place to be looking (and including Kata Noi beach to the south.) I agree that there are some great options nearby island, but personally, at this time of year, I did not choose. Have a great trip.
