4 weeks ago I stayed for some days at the On8 hotel.
This stylish designed hotel opened just 6 months ago.
I payed 1800 BHT a day including breakfast (discount for early-bird booking).
The location is just perfect: directly located at the Nana BTS-station. Soi 11 with lots of club is just over the road. 1 Minute walk to Lolitas; 10 minutes walk to the Nana Plaza.
All rooms have a huge flatscreen TV with 85 channels. They don't charge a joiner-fee. In the lobby you can surf in the internet for free.
