France-based hotel price negotiation portal Barteo.com has rebranded itself as 365Nights.com, in a bid to expand its presence in a fast growing market.

It has also launched a brand new version available on tablets and mobiles.

Launched in 2013 by Thomas Hiley and Tony Grippon, the Parisian travel agency allows potential guests to negotiate room price directly with the hotel and in real time, before making an actual booking.

Based in Paris, 365Nights.com serves over 400 properties in France.

365Nights.com founder Tony Grippon said the company is looking to commercialise around 800 hotels by the end of the year.

"We visit every hotel and we make sure that it meets the needs and demands of our customers."

"We visit every hotel and we make sure that it meets the needs and demands of our customers. Our goal is to have a consistent selection of hotels on each destination," Grippon added.

In 2013, around 65% of the reservations were made by business customers and the company wants to continue this trend by offering more 3-star to 5-star hotels located in city-centres.

365Nights.com has also launched an exclusive partnership with Verychic, a flash sale website, in order to highlight the hotels every day.

"We make sure that our hotel partners have an exceptional and additional visibility with a constant audience of 2.5 million members. Then we are responding to their need for diversification," explains Thomas Hiley.
