The apartment hotel's name is derived from the words 'atrium', meaning space, and 'zenon', which is the name of the founder of the ancient stoic school of philosophy based in Athens. From the first day of operation, the hotel's policy has been to give the best service possible to prospective guests and keep them returning every year. Renovated in 2010, this family-friendly apartment hotel welcomes guests in a lobby with 24-hour reception and check-out service. Facilities include air conditioning, a hotel safe, currency exchange and lift access to the upper levels. There is also a TV lounge, café, bar and a breakfast room on the premises. Conference facilities are available to business travellers and all guests can take advantage of the Internet access, and the room and laundry services on offer (the latter two incur additional fees). Those guests who are arriving by car may park their vehicle in the hotel's car park. Bicycles can be hired from the hotel.

The hotel serves lunch à la carte.
