Hotel Secession an der Oper

This hotel is in an excellent location! It's walkable to many parks, shops, restaurants, and museums. The rooms were large with beautiful hardwood floor. Our 2 issues: 1. ants. We had ants in our room. We did not notify housekeeping as we have young children and did not want them to spray/address the issue during our stay as we believed it would be troublesome to shift nap time or leave the room. 2. We had somewhere to be at 3 pm. Unfortunately, there was a misunderstanding about the time or so I thought. One staff member told me 2:45 pm was written down instead of 2:35 pm. However, at 2:50 pm, they told my husband nothing was written down so they would order us a new taxi. My husband hates being late, so this was disappointing to us.
