I will let David reply, but I stayed there in February and had no problem with noise.

There are THREE construction projects near by.
An older building to the right of the Ramada is being remodeled.
A new tower is under construction to the right of that building.
On the site of the old seafood restaurant.
And I saw a crane near Bangkok Children's Hospital.
Seems that BKK is coming back to life...

Many new businesses along Suriwong road.
Hugh drugstore where McDs used to be. At Patpong.
New coffee house across the road.
And lots of new massage places. Not the kind we enjoy!!!
HUMMM, Suriwong is loosing it's character...

Cheers!!
