After 5 days in Koh Phi Phi, which I found enough because it's a very small island we traveled back to Phuket to spend the weekend. It was exciting to be in a big city for a change, but it was also overwhelming especially because of the amount of tourist. We couldn't find beaches comparable to the ones in Koh Phi Phi. Most of them weren't as clean, or as serene and calm but we heard that if you are looking for a beautiful beach Kata Noi is supposedly one of the best.
The best way to get around in Phuket is by renting a scooter. It is much cheaper and more convenient. Otherwise take the local bus, it's also very cheap and you get to see so much. I wouldn't recommend to take taxis, they are way too expensive and you dont get to experience that much.
We stayed at Phuket town in a mediocre hotel called Sino Imperial, the location was excellent but the hotel itself was not the best. It's a good choice if you are staying for a short period and you want something on the budget side.
Phuket town is charming and not at all as touristy as the Patong area. The area has plenty to offer: small cafés, vintage shops, cute restaurants. I fell in love with the food at the Eleven Two & co. restaurant. A must try if you are in Phuket town, and I would recommend their salmon dish.
Phuket weekend market also known as the Naka Market, is really worth a visit. It is located out of Phuket town and close to the Naka temple. The market offers an endless list of good (clothes, accessories, food, souvenirs, beauty care, animals etc..). Make sure to dedicate half a day because it is impressively large and don't be shy to bargain. We didn't have that much time but I powered shopped and bought so many things for so little money.
All prejudices about Thailand are all gathered in this area and especially on Bangla Road: the prostitution, the lady boys, the sleazy western tourists, the ping-pong shows, the thai massages, the tuk tuks and so on. Patong is the tourist Mecca of Thailand, and is definitely not my favorite place, the chaotic atmosphere can be overwhelming.
One week was definitely not enough for Thailand, I am going back for sure to explore more of this beautiful country. I would like to visit more islands and experience Bangkok.
