The hotel was clean and looked amazing. Apart from the first employee we talked to, he was great, the others were awful. Waited ages for a drink until another employee walked by. No “how was your stay” or “thanks for staying” or nothing when we checked out. Just a rude “printed receipt or email.” ...
