Croatian hotel group Maistra has opened its latest property - the 248-bedroom Lone Hotel in the city of Rovinj.

Designed by architects 3LHD and Silvijo Novak, the HRK335m (US$61m, 44m euro, £39m) hotel's facilities include a 1,700sq m spa and wellness centre, restaurants and conferencing space. It is the first Croatian hotel to join the Design Hotels scheme - a membership scheme for design-led hotels.

The spa, designed by The Netherlands-based 4SeasonsSpa, boasts eight treatment rooms and a sauna area with a scented steam sauna, Finnish sauna and infrared sauna.

There is also an indoor fresh-water swimming pool with special hydro-massage effects, a relaxation area and a health and fitness club.

The spa's signature spaces are the two specially designed and connected rooms, so called "sunken rooms", offering floating and relaxing on hydro massage beds and chairs.

The treatments at the spa are focused on facial and body treatments, various massages and healthful baths with special emphasis on individual approach to each guest.
