When my friend had a maternity check-up last October, I was able to go with her together with other friends in this place. There are a lot of businesses in Gewerbepark in Regensburg. You can also find various clinics inside with different specialization. I am not quite sure if there are luxury top rehab centers nearby but I know that there are some in the city of Regensburg.
My last visit to this place was just the other day when a family member had a check-up in one of the clinics there. I went walking around while waiting for the check-up to be done. I ended up window shopping too. This Commercial Park has around 300 businesses and companies with around 5,000 workers. Around 15,000 people visit it everyday.
