We had a lot of trouble using the WiFi, it was VERY slow, and sometimes didn't work at all. We shutdown the router and repowered it, but that seem to only help for a short time. Enjoyed all the space in the rooms, but would hesitate to stay here if I needed to count to be able to access the internet. If the WiFi was fixed it would up my rating. If you do not want access to the internet, you could up the rating to very good.
The location is great, right on the square beside the Frauenkirche, and very close to the old green museum.
The apartment we had was large, and had a big entry way. The kitchen had an electric kettle and toaster, small refrigerator and a 2 burner cook top. If you were staying for a longer time you should know that there was no dishwasher, oven or microwave. There are no stairs to deal with when bringing in your luggage, as entrance is at street level, and there an elevator at that level. The elevator was large as compared to some in Europe. The stairs have good lighting.
There is a safe in the room, but it is fastened to a shelf that just lifts out of the wardrobe.
The bathroom was large, and had a tub. The tub sides are high, so you need to take care when stepping in and out. The washing machine is located in the bathroom. It is not a large one, and needs to have a light load in order to spin properly. There is a drying rack supplied to hang your clothes on.
The breakfast is optional, and is located in another building. We found other options so can't comment on it.
There is construction in the area, but on the days we were there it didn't bother us. Depending on what is being done on the construction site, that may vary.
