I walk past it almost every day after work. The girls sit the reception area which you can see as you walk past. Its very open-plan. The building used to be a Letting Agents. There's also one opened up on Chatsworth Road Chesterfield I've noticed. Don't know if anyone's got any experience of that one.
I went there last summer,the owner did the massage, a very young thai girl,no extras offered and signs on the massage room door saying not to ask for anything else
