My wife and I stayed here with our two daughters in July 2014 for about 5 days..
This is a spacious apartment with a bedroom, kitchen cum dining room , living room and a spacious indoor laundry area.
This is set in a lovely garden and is a short walk through some lovely woods into the old city area of Baden Baden ... We were able to walk to most of the attractions such as lichtantaler allee, old city area, the baths, new castle etc. The only downside is that it is a bit far from the train station which is outside the Baden Baden city area. However we did not find this to be an issue as there are sufficient taxis and good connecting bus service to the city centre area,
However if you have a lot of luggage I would suggest taking a cab or requesting Mr Hammer for a pick up.
Overall we loved the place and would definitely stay here again.
