suriwongse is at the bottom of loi kroh road enough said. It is a nice place but it is a little too close to the night bazaar for my tastes. (congestion and annoying tuk tuk drivers)
I really like RCN court on MoonMuang soi 7. It is Relatively cheap 600 baht and the rooms are simple but nicely airconditioned and clean. Girls no problem at all. Solid internet (high speed and 20 baht/hr) on site good food and good laundry. NIce neighborhood inside the moat. 5 min walk to thapae.
