The hotel would be ok, even as old as it is, but the service and staff can definitely turn an average experience in a bad one. Even small problems are difficult to solve with, including keys, internet, booking, basic questions... Better to pay just a little more and get another hotel around Silom Road and region since it's a very nicearea with many restaurants, malls and convenient location (just avoid stay very close to Patpong if you are in a family trip since it's also the "Red District" of the region).
