Nothing I can remember. Maybe the lift was too small, but people can deal with it. Some rooms are in middle-floors, but a question of no more than ten steps.
Great restaurant. Very nice view and good food. After having lunch there, we went back on dinner. Very nice staff, mainly in the restaurant and breakfast room. The restaurant manager is great, the waitress too. At front desk, personnal was also good. We stayed in the annex, it's new and comfortable. Close to the harbour, but you have to negociate some hundreds of meters and maybe a staircase (depends on the way you take). Heraklion itself is not that great, but Knossos is; I'm convinced there are no better options in the city.
