Have never seen Angela, I always stick to Savannah.
The spa is decent, not like BP but not bad - yes it's clean. The spa is in an industrial area so going at night for the first time it could be easy missed or make you feel hesitant about going in. Nice entrance and waiting room - comfortable and welcoming. Everytime I've seen Savannah its been in the same room (first one around the corner). The room is small, just a small four legged chair, the table, a small sink (a little on the cheap side) and a decent shower. I'm sure they must have bigger better rooms but I haven't seen it.
Have always showered alone. Bodyslide from Savannah is top notch - do a search for more details.
