The staff at this property were inconsistent and may need additional training. At check-in, I requested to merge two reservations. I was told my options were to 1) check out and check back in again during my stay or 2) I could merge my reservations for a fee. I opted for option #2, to avoid disrupting my trip. I was still locked out of my room the day my original reservation ended, so I did not save any time in the long run. The night before my flight out of Munich, house keeping kept calling me to check on me? I had just spoken with the front desk a few hours prior, and I feel that it's inappropriate to repeatedly call a quest at night time. If the "do not disturb" sign is up, how is that an invitation to call someone repeatedly after dark? Finally, I prepaid for my room reservations, and they still tried to charge me again. I don't trust that this is worked out, so I will need to monitor the situation closely. All in all, I felt this hotel was quite disorganized. There are nicer hotels in better locations in Munich.
