This apartment is beautifully finished, and is very comfortable (apart from the lack of air conditioning, but that is to be expected when staying in old town). Having a greeter meet us at the apartment and let us in is very nice too. However, the preparation of the apartment for our stay left much to be desired, especially considering the price we paid per night.
We were a party of 5, but when we arrived there was only bedding for 3. They are very responsive to messages, which is great, but we were instructed to find the extra bedding ourselves. The dishwasher was also full (clean, at least), so I had to spend the first hour at the apartment putting together bedding and unloading the dishwasher. (It made me wonder why I was paying a cleaning fee.) In addition to the bedding issue, there were not any kitchen or bathroom hand towels, and there was no extra toilet paper beyond what was on the dispenser. The following day, we did finally get a delivery of the missing items we needed, but unfortunately our experience was a bit soured. Finally, there were only two fans provided, though there were 5 of us so obviously we were going to have 3 sleeping spaces. There was a heat wave while we were in Munich, so we were pretty uncomfortable at night without adequate air circulation. No extra fan was provided despite our asking for one.
I think this would be a 4-5 star apartment if we hadn't had all the issues with the amenities. And be warned: there is no microwave for easy meal prep!
