The applicants alleged that the prison had held 2,400 prisoners while it had been designed to accommodate 700. The applicants had been detained in wings A, B, D and E in various cells which all had measured 9 sq. m, including the sanitary facilities, and accommodated four or five prisoners; the living space for each prisoner had therefore been approximately 2 sq. m or even less. Cells designed for one person had had two beds and two or three worn-out mattresses on the floor. 9.  The toilet facilities had been partially separated from the rest of the cells. Access to natural light and ventilation had been inadequate. In addition, there had been insufficient heating and hot water. Cells had been dirty and overrun with cockroaches and other pests and no attempt had been made to exterminate them. Healthy prisoners had been held together with sick prisoners, resulting in their exposure to contagious diseases. There had been no adequate medical care, in particular as regards psychological and physical health. 10.  The inmates had been confined to their cells for sixteen to seventeen hours per day, as recreational or educational activities had not been provided. More specifically, inmates had been required to stay in their cells as follows: from 6.30 p.m. (on average) to 8.30 a.m. and from 11.30 a.m. to 2.45 p.m. every day. They had had to take their meals, which were of poor quality and nutritional value, inside their cells. 11.  Moreover, the prison had been understaffed and had not been able to secure the prisoners’ safety. 12.  On 21 June 2013 the applicants along with other prisoners lodged a complaint with the prison authorities, protesting about their conditions of detention, but did not receive any reply. 13.  The Government asserted that irrespective of the number of prisoners in each cell, which in any case had not been constant, prisoners had had access to a large yard daily from 8 a.m. to 12 p.m. and from 3 p.m. to thirty minutes before sunset. The prison had had a central heating system and hot water had been available on a daily basis in the morning and in the afternoon. Prisoners additionally had been able to use electric heating devices. Every cell had been furnished with a washbasin, a toilet, wooden shelves, a table and chairs. 14.  All the cells had had a window ensuring sufficient light and ventilation. The cells had been regularly disinfected and had been cleaned twice a day by cleaning crews consisting of detainees. All the applicants except applicants no. 4, no. 17, no. 26 and no. 28 had been engaged in this activity. 15.  As regards prisoners’ meals, the Government submitted the menu of two random weeks to demonstrate that they had been comprised of a variety of food. Meals had been served in the cells and prisoners had eaten at in-cell tables. 16.  Prisoners had been able to play sport and each prisoner had had a personal television set with a headset. In addition, they had had the opportunity to take up one of the 640 jobs available, to take part in educational courses or to attend the “second chance” school. The renovated room of the reading club and the events hall of the “second chance” school had been available as recreational areas. 17.  All the detainees had had access to the prison’s infirmary which had been open twenty-four hours per day and there had been twenty doctors of different specialities, including two psychiatrists who had offered consultations to the prisoners. In cases of emergency, inmates had been transferred to the Korydallos Prison Hospital or to an external hospital.
