I use North exit side of LH, find pretty good, friendly receptionist. Cheap, Spacious, great value, damn close from the station. If you want to save as much, I recommend Savoy at the corner.
Warm Orange room setting. Weekdays from 3,500.- for 2 hours. Weekends higher rate. When full, ask for ones that are cleaning.
I also like EXE, from 5,000.-. Those two are my heavily used LH in Uguisudani. I find South side seem smaller size LHs, one after another. Not comfortable going into entire sets of LH vally. But the North exit side, No cops around.
