The company was established in Leeds in 2006 and as well as three hotels in the city also owns sites in Manchester and Newcastle.
The Roomzzz venues feature what the company refers to as the best things from boutique hotels and the best things from serviced apartments - as well as the usual apartment features, the room rate includes breakfast, a concierge and room service.
Announcing the two new locations for the brand, Mark Walton, head of Roomzzz Aparthotel UK, said 'consistency, service and location' were the secrets to the success of the concept.
"This from an operator who has introduced the Roomzzz concept to the UK six years ago and has seen occupancy levels soar to a consistent 87 per cent across five sites and who is happy to reveal in 2012 the brand is running 16 per cent up on 2011," he said.
The firm uses a loyalty card scheme to build a customer base of regular guests - the entry-level card is free to all while two further cards are awarded when people return a number of times. All three cards offer increasing levels of discounts.
"New guests and regular guests of Roomzzz are feeding back to us of their delight to experience a Roomzzz Aparthotel in multiple cities – our real time loyalty scheme is playing a huge part in rewarding guests and we're seeing huge peaks in repeat visits across all sites as a result.
Earlier this year the firm expanded their Manchester property and opened a £6m site in Newcastle. Walton revealed new city centre locations sites in both Liverpool and Chester would not be the company's only new opening activity in the next year - some of the business expansion is driven by franchising.
"The Roomzzz brand is making unashamed progress in the industry, we're keeping our heads in terms of offering and giving our customers exactly what they come to us for which is impeccable hospitality in key locations for a price that makes sense whatever your reasons are for travelling.
"To illustrate this Newcastle City - the brand's latest opening hit the number one spot on TripAdvisor for hotels in Newcastle in under four weeks.
"It's an exciting and profitable time for us and we are focused on making our mark in innovation and more new openings over the next 12 months," he explained.
