I have just returned from a week in Kalamaki.  My mum and I booked to stay at Dina's Apartments and phoned before we travelled to explain we wanted twin beds.  When we arrived, we were given a double bed and told that all rooms were like this, even though we found out later that twin beds were available. She offered us an extra single room at €35 per day.  We refused to pay as the Venus Hotel only charges €30 per day and it has a pool, bar and other facilities.  We had an extra bed placed in our room, but this made space extremely limited.  We were also given a ground floor apartment even though we had asked for a first floor one. The first night we were there, the electricity box came away from the wall and I had to re-wire it to get the electricity to work!  The one shelf provided was hanging off the wall at a 45 degree angle.  The beds were changed once during the week.  We were only given clean towels when we asked for them (and one each, not two!) and we had to buy our own toilet rolls.  We were told the rooms were cleaned every other day, but people went into our rooms on other days without us knowing, because items were moved and rubbish taken away, even though beds were not made.  Air conditioning was available but at a cost of €40 per week, which we found too much, but the room was swelteringly hot and we sweated constantly.  Costas Pool Bar was recommended to us by Dina, but we found it ridiculously expensive - €17 for a breakfast of 3 toasts, two coffees and a tea.  We also had to endure constant observation from Dina herself, who always seemed to be around every time we opened the door and this made us feel uncomfortable.  On our last day, we were told to vacate the room at 10am, but at 9.15am (while I was still getting dressed!) she came into our room and said she had to take the extra bed away.  I had to move my suitcase and clothes off the bed so she could take it away!  All in all, this could have spoilt our holiday, but I didn't let it.  However, I would not recommend anyone to stay there.
