We had a wonderful time in this pleasant apartment. There are 2 bedrooms that each have a queen bed (2 split twins) and a bunk bed. There is no living room, but the roomy kitchen has very comfortable chairs and a long bench. The bathroom is HUGE!! with both a tub and large stall shower. The entry is a large, welcoming area.
Even though the hosts speak only a little English, we were able to communicate just fine with Google Translate and they were prompt and attentive in their responses. I think they own several large rentals in the area. There was a parking space just around the corner from the apartment.
It is on the second floor, so be sure that stairs aren't a problem for you.
We thoroughly enjoyed our 3 night stay. You'll even get to see the chickens out your windows! :) I would highly recommend this rental for a large group. It is centrally located - we flew into Stuttgart, out of Frankfurt and took day trips to Heidelberg and Luxembourg. It is also in the heart of the wine region with lots of wineries within easy access.
