I used to be ('04-'08) a fairly regular punter at their Boston place. It was a unit in a mini industrial area. Pretty discrete and easy to get to. One big room with double bed, mirrored ceiling and corner unit couch. Some good English girls, EEs and the usual minging WGs you get in their types of places. Pre-internet so it was a case of phone up, listen to the discription and take a punt (literally!).
The Lincoln place moved around and was a bit more shady, few police issues over the years. Same girls though.
