We arrived at Hotel Ground27 earlier than the check-in time. Hence, we asked the request of keeping 5 big luggages and 2 small luggages in the hotel as usual as doing this in other hotels. Hotel staff asked us to keep all the luggages in the lockers and total we need 6 lockers. A fast action from the hotel staff, he only asked us to insert the password on the locker screen. We just think that this hotel is a modern and well-equipped hotel, so furnished with lockers to the travellers. However, when we returned to the hotel at night. The hotel staff asked us to pay for the locker fee. Oh my god, why nobody told us the lockers to be charged. We knew nothing about how much per hour to be charged. If we knew that in advance, we would not keep our luggages in the hotel instead of keeping in our 8-seat private car as well as we would not have dinner around the hotel. Unexpected charges made us feel very unhappy and also the staff was rude to explain to us.
