I can only review my personal experience, the kefalonia grand is advertised as a 4 star hotel, i was flying solo so opted for a double room which i paid extra for a lateral sea view, on arrival i was greeted at reception and immediately asked for an extra 100 euros for my 10 night stay, I had to wait and hour until I could get to my room, I was briefly shown around and told i get a free small bottle of water per day, On closer inspection the room was bland, double bed, wonky tv, shower room and wardrobe which contained a tiny fridge and safe, light fittings were in disrepair and the shower room was disgusting, paint peeling of the ceiling and floor, mold stains in the shower and toilet, no considering this was supposed to be a 4 star grand luxury boutique hotel i expected a lot better, tea and coffee making facilities at least, Having complained to the receptionist I was told nothing else similar was available so I contacted the operator who just wasn't interested, The breakfast was fantastic as were the staff but I never dined there as a protest, Argostoli is a beautiful place but the hotel ruined it for me , the room had an air-conditioning unit but after 3 days I developed a raging cough and cold which further compounded my misery, having returned home i contacted the operator who is still investigating, the pictures show the issues and also the fact that the hotel isn't quite finished.
