I arrived the apartment at 9:30am and plan to store the luggage at reception then go out for sightseeing. Unfortunately there's nobody at the reception, no one answer the door bell nor pick up the phone. I have to take my luggage with my day-trip.
Later, I asked the reception whether they can help to store my luggage after check-out, they can only provide service after 10:30am, and they are not willing to help at earlier time, although they are living on the next building.
I understand that many apartments have to check-in after 3pm, but I don't expect such unwillingness service even for picking up phone call in day time. If there is such time constraint, it should be written on the website so that tourist is aware and can follow their rule.
