The staff are very friendly, but that's about it... I live right next door to the Opéra in a huge city apartment that does not have a guest room, though! That's why I usually accomodate my visitors in a hotel room. We've tried the Opéra once, twice and for the very last time in July 2010.
I would never accomodate someoene there again. The owner of the Opéra is the same as of the Restaurant Gandl next door. He inherited the hotel and the restaurant. All he does is to take the money out but not to invest a cent in either the hotel or the restaurant. We've been through quite a few rooms at the Opéra. You will not find a single room that is in good shape. The fabrics and wallpapers in the "lobby" and rooms are all old and worn down. The mirrors all have cracks. The bathrooms urgently need renovation. Also, the entire house is clairaudient as can be. When someone walks in the hallway or shuts a door even quietly, you can hear every step or movement. There is no aircon and in the summer and it gets really hot and sticky in the rooms.
My last visitor was supposed to stay for three nights and moved out after one night. She was on the same floor with an Arabic family with little children who rented five rooms on that floor. The doors were slammed all day by the little children. They kept on running up and down the hallway, sreaming and playing. We complained at the front desk. They did nothing.
At least they let my visitor move out after the first night and didn't charge the second and third booked night.
The Opéra charges for a single really small, uncharming room about 190 Euros/night. It's overpriced as can be for what it is. Obviously the have not understood that there are small brand new hotels in an even better location (down-down-town) that charge between 160-220 Euros and that are well maintained. Try the Cortiina (double ii) or the Louis Hotel. They are both stylish and fine. They promise big and deliver big. If you are on a smaller budget try the Adria Hotel around the corner from the Opéra. It's only a three star and you can get it for about a 100 Euros but they are halfway modern and extremely nice. The Opéra is just a run down ramshackle hut and the owner doesn't know what the word "investing" means.

A romantic weekend at the Opera? Well, almost. The ratings on Tripadvisor and the location convinced me to give it a try. It is very well located, on a very quiet street but next to Maximillianstrasse shopping. The facade is lovely and the ambiance is romantic. But... they are renovating the courtyard, so there is noise and no access. Plus, there is this thing with the beds. Despite my specific request, the first room had two single beds pushed together (opposite problem to another reviewer). Service was good - they immediately offered another room. However; the second room (#37) was tiny, smelled funny and was a bit run down. At least it had a balcony. We enjoyed the charm but recommend that you call to get exactly what you want as the quality is very unequal.

The Hotel Opera is a beautiful, little hotel with a lot of charm. We arrived at the hotel for our honeymoon after a long over night flight and a full day touring Dachau. The hotel is located down a little side road away from the main tourist areas, but close enough for an easy walk. If your looking peace and quiet this is the hotel. If your renting a car be aware that parking is on street and pay. The front desk staff were a little stuffy and short with us, but easily forgivable. While the room we stayed in was very small it had a very nice bed, plenty of storage space, a beautiful and spacious balcony with couch, fresh fruit, plants, and movable glass enclosure for winter use. The bathroom was tiny, but very unique.

Our bed unfortunately had a blood stain in it. With in fifteen minutes the cleaning crew was up there with fresh sheets and blankets. Breakfast the next morning was the typical Bavarian lunch of bread and fruit., yet was presented in a very elegant setting.

The charm, decor, and peacefulness certainly make up for this hotel's short comings.
