Suiteness wants to double the number of cities on its roster, using funds from $5 million capital-raise it has unveiled this week.
The booking platform for luxury and apartment-style hotel suites says the Series A investment will help it launch in a further five cities by the end of 2017.
Backing the company are co-leads Bullpen Capital and Global Founders Capital, with HVF, YCombinator's Continuity Fund, Kima Ventures and Altair Capital also participating.
The company was formed in 2014 with a vision to create a members-only service that allows travellers to secures deals on hotel-run luxury suites and properties, initially in the US.
It has since grown to include London as well as existing destinations such as Miami, Las Vegas, Los Angeles and New York.
Orlando is scheduled to be the next location in the roll-out programme of new cities on the service.
It claims to have 100 hotel partners including SLS Hotels, Viceroy, Dream Hotels and Caesars Entertainment, giving it a portfolio of around 30,000 luxury products.
Suiteness says it is adding a new member "every four minutes", with a total membership number of almost 50,000.
The company picked up a seed round of $1 million from Structure Capital in December 2015.
Bullpen has previously invested in Zynga and About.me, whilst Global Founders has backed TravelBird and HappyCar.
Suiteness CEO Robbie Bhathal says:
"Demand has accelerated at a much faster pace than we anticipated and forced us to expand ahead of schedule.
"We launched Suiteness to fill a growing gap in the travel market for families and groups who wanted the space of a home or apartment, yet didn’t want to sacrifice the amenities of a 4 or 5 star hotel."
