We found Carmen's place to be absolutely charming. The apartment was wonderful, comfy, and very picturesque. Carmen was easy to communicate with and they provide a map of the local area to help us navigate and find good local food. We highly recommend Aunt Benny's for any meal of the day, it's just a short jaunt from the house.
The beds were very comfy and the shower was the best we'd found in Europe(there are some weird ones!). If you get lucky you might get to be greeted by an adorable kitty cat sun bathing in the garden in the morning!
All in all, we would definitely recommend Carmen's place to anyone who wants to get a bit out of the city center and experience real Germany.
