I stayed in Hotel Cortiina for one night on a business trio in September 2012. The hotel is very stylish with excellent designs and located very centrally but quit at the same time. When I reserved the room I was "warned" that the room would be very small and it was small indeed but it was spotless and still had all the comforts and was rather beyond my expectations. The staff was attentive and helpful, too and they served a pricy but excellent breakfast.

Our room 411 was very large and modern. Loved having a bathtub. Location could not be beat in terms of marienplatz (the center of town plaza). Breakfast and lounge were fabulous. The only detriment I found was the Internet was spotty and slow at times

Pros: helpful staff, clean room, central location, relatively stylish and comfy, free wifi.
Cons: shockingly noisy
This is tough. The hotel is excellent but I cannot give it that rating. The staff was very friendly and quite helpful. We had two rooms in the "annex'" which is a separate adjoining building that contains four rooms, as well as some unrelated business space. Thus, getting from the street to the rooms was kind of odd (either direct entry from the street or through some of the back corridors of the hotel). The front room was very nice indeed -- quite large, big comfortable bed and a bathroom with heated floors. The rear room was also comfortable, but very oddly laid out - kind of L shaped, with the door at the angle which, when opened, cut off the two halves of the room. Nonetheless, if that was all, it would rate four stars (overall quite good, with a couple of oddities). But the noise in the front was just dreadful. There is a bar just across the street called the Rock Box and another right under the room called Americano. Right under the windows of the room are benches. People leave the bars to sit on the benches and smoke. Drunken 20 year olds would sit on the benches and scream (no exaggeration) at each other. Until 2:45 am. Every night. Despite two rows (!) of double paned windows in the room, it was shockingly loud. I can only imagine what it would be like in the summer when you need open windows. The back room, facing the hotel courtyard, was quiet. I admit I did not ask to change rooms, which I certainly should have done. But I cannot have been the first to have this issue. Lest you believe that it won't happen to you, from what I can tell, there is also a bar on the front side of the hotel, so I am going to imagine it is no better there either, Courtyard facing room is your only option...but in warm weather it appears that the hotel bar has a seating area out there, so my guess is that it is noisy there in the summer months. Alas, despite a central location, nice rooms and a helpful staff, I won't stay there next time.

The first thing to say is that the staff on reception at this very central hotel were great; very friendly and helpful. So our hopes were high as we headed to our room in this 4 star hotel. However when we stayed one night at the Hotel Cortina in Munich in late December 2012, we were not impressed by the accommodation. When you pay 208 Euros for a room (including breakfast) you do not expect cheap lumpy and very uncomfortable pillows, thin towels and no toiletries except liquid soap and moisturiser from bottles attached to the wall, plus a very basic shower with mediocre water pressure. We stayed in room 420 on the fourth floor (over-looking the street) and the water pressure may be better on the lower floors.
This is a hotel conceived by accountants not hoteliers. If you like bare white walls with non-descript wall-paper, no rugs on the parquet floor, inadequate bathroom lighting, and poor double-glazing, then this is for you. The noisy street below made it impossible to sleep with the windows open. Additionally, the heating was intense. We did telephone reception for advice on this point and were assured that they would turn off the heating, however this proved impossible. The curtains and blinds were also thin and cheap with no blackout facility which made the room very bright during the night. This would be an even greater problem if staying during the summer months when the sun rises very early.
On the plus side, the room was a decent size with a desk (only one power-point however), there was adequate storage for a short stay. And it is easy to access this hotel by public transport. Also, the buffet breakfast was excellent and the breakfast staff were very friendly and helpful and could not do enough for their guests. However, we would not stay there again because of the poor standard of the accomodation which we felt was very over-priced. We moved to the nearby Hotel Platzl upon our return to Munich a few days later, which was much better value and very comfortable.
