townhouse sector

Our company is called "Veritas"- Latin for truth, which falls into line with our ethos of offering an honest and personalised service. We believe in consistency and in being straightforward with our candidates and clients. The decision to start Veritas in 2001 was prompted by an urge to build a consultancy that offers an efficient but dynamic approach to recruitment. We value the "personal approach" and pride ourselves on working with total integrity, confidentiality and honesty. Most assignments come from the four and five star hotel sector, whether they are independent properties, small groups or large corporations. We work with the 'boutique' hotel and townhouse sector as well. The common denominator with all our clients is "quality”.

Could you tell me what "townhouse sector" means here?
